Active transport vs passive transport

Active transport and Passive Transport are the processes by which molecule transport across the membrane. The main difference between the Active transport and passive transports required energy to occur the process and concentration gradient.

	Active transport	Passive transport
requirement of energy	Active transport requires the energy to movement of the molecule.	Passive transport does not require the energy.
concentration	Active transport happens against the concentration gradient.	Passive transport happens along with the concern gradient.
Example	Endocytosis , Exocytosis and sodium-potassium pump	facilitated transport, diffusion, and osmosis.
Molecule transport	Active transport pass the large molecule against the concentration gradient	Passive transport pass He small molecule along with concern
Selectivity	Active transport is highly selective.	Passive transport is not selective
Inhibition	Metabolic inhibitor may inhibit the active transport	Metabolic inhibitor does not affect the passive transport.
Speed	Active transport is rapid process.	Passive transport is a slow process.

difference between Haemoglobin and Myoglobin

Haemoglobin and the myoglobin are two molecules in our body which carry the oxygen in our body. But there so many difference between the Haemoglobin and myoglobin. There is physical and the chemical difference between the Haemoglobin and myoglobin. 

Following the difference between the Haemoglobin and the Myoglobin

	Haemoglobin	Myoglobin
Nature	Haemoglobin contain four polypeptide chain	Myoglobin is single polypeptide chain.
Structure	It has tetramer Structure.	It has monomer structure.
Binding	Haemoglobin bind with four oxygen molecules	Myoglobin bind with only single Molecule
Binding affinity	Haemoglobin have high affinity to bind with oxygen (Tightly bind with the oxygen)	Myoglobin have less affinity to bind with  oxygen
Availability	Haemoglobin found in blood	Myoglobin found in muscles.
Function	Haemoglobin provide the oxygen to the every cell of the body,	Myoglobin  provide the oxygen to the muscles cells.
Known as	Hb	Mb

Endocytosis: Types of Vesicle transport

Definition:

Endocytosis is defined as the process in which the molecule transports into the in form of vesicles.

 Endocytosis is the process in which the vesicular is formed and it supplies the material inside the cells.

The large molecule transfer into the cell via the endocytosis process. The molecules or the material which can not be transferred into the cell through the cell membrane that type of material transport into the cell by the endocytosis.

The plasma membrane folds inside the plasma membrane and form the hollow space which fills by the fluid or the material which needs to transport inside the cell.

Definition of Hematocrit

Definition of Hematocrit:

-The percentage of total blood volume occupied by the red blood cells is called as the hematocrit.

-The hematocrit is expressed as a percentage. 

- The normal range of hematocrit in adult male is around 40 to 54 % while in adult female is around 38 to 46 %.

-If Hematocrit lower than the normal range it indicates the anaemia. While Hematocrit is higher than the normal range it indicates the condition known as Polycythemia.

Red blood cells (erythrocytes): definition and characteristic

Definition of Red blood cell (erythrocytes):

Red blood cell is defined as the concave shape blood cells which are responsible to transport oxygen and carbon dioxide gases into the cells.

Characteristic of Red blood cells:

-Red blood cells are the concave disk by the shape.

-Red blood cell disk has diameter of approximately 6 to 8 um (Micrometer).

-Red blood cells are the flexible and mature cell does not have a nucleus.

-The shelf life of the RBC is 100 to 120 days. Red blood cell contains 40 to 45 % part of the cells in the blood.

-Red blood cell contains the haemoglobin which is responsible for transport the oxygen to the different cell of the body from the lungs.

Each red blood cell contains about 280 million haemoglobin molecules.

-Haemoglobin made up of protein and iron. The protein is called as globin. Globin protein contains four polypeptide chain. And the iron metal part of the molecule is known as heme so combine molecule is known as the Haemoglobin.

- Red blood cells are tare as it passes through the thin capillaries as red blood cells are squeezed into the capillaries

Function of Red blood cells (erythrocytes)

Red blood cells (erythrocytes) are the most important cells of the body which have so many functions in our body.

Following are the function of the red blood cells

-The main function of the red blood cell is to carry the oxygen to the different cell of the body from the lungs. It also carries the carbon dioxide to the lungs. Vein carry out the deoxygenated blood while the artery always carries out the oxygenated blood.

-Red blood cell contains the haemoglobin which regulates the blood pressure into the body.

- Under some circumstances, Haemoglobin release the nitrogen oxide which is a gaseous hormone.Then release of nitrogen oxide cause the vasodilatation.

- Dysfunction of the RBC causes the Anaemia.

What is the composition of blood (Component of Blood)

Composition of Blood:

Blood has two components

1.Blood Plasma

2.Blood cells 

Blood Plasma:

-Blood Plasma is liquid matrix available in blood. It contains the dissolved substance in it.

-55 % of blood is made up of Blood Plasma.

-Blood plasma is made up of around  91 % of water and around 9 % of solutes.

The solutes are the protein, Electrolytes, Nutrients, gases and waste products.

Blood Cells:

-Blood cells and its fragments are the elements of the blood. when blood gets centrifuge in tube all cells and its fragments settle down at the bottom of the tube.

-45 % of blood is made up of Blood cells.

-Mainly 03 types of blood cells are present on blood

1.    Red Blood cells

2.    White blood cells

3.    Platelets

Blood is considered as connective tissue .lood is one of the important elements of the body.Blood having some unique characteristic property.

Following are the characteristics of the blood.

-These blood cells are suspended in a liquid matrix the liquid matrix known as Plasma.

-Blood is formed by around 45% of blood cells and 55% of blood plasma.

-Blood generally accounts for 8% of the human body weight.

-Blood is denser and viscous than the water

-The pH of the blood is around 7.4(Alkaline).

- The blood volume is  4 -6 liter in average size adult. ( 5 to 6 liters in average male 4 to 5 liters in average female)

-In blood, Red blood cells constitute about 45% of whole blood, plasma about 54.3%, and white blood cells about 0.7%. Platelets are less than 1%.

- Haemoglobin is responsible for the red color of the blood. 

- The temperature of the blood is around 38 ° C (100. 4 ° F).

Main Function of Blood

Blood is the one of the most important element of the body which one of the connective tissue. Blood has so many different functions which require for the body. Transportation, protection, and regulation are the main functions of the blood.

 Following are the three main function of the blood in details :

Transportation

Blood carries out the oxygen and supply to the cell which is used to generate the energy in cellular level and also carry the carbon dioxide and remove from the body.

It carries out the nutrient and supplies it to the different cells of the body

Blood also removed the waste material from the body.

Blood also transport the hormone which regulates the different function of the body.

Regulation:

Blood maintain the pH of the body. also, maintain the body temperature. Also, carry out the different hormones which also regulate the different functions in our body. Blood also maintain the pressure of the body

Protection

Blood clot into the body and protect from the excessive blood loss.Clotting of blood process help into the healing the injuries. Blood also protect from the disease. Blood also contains the antibody

Types of blood cells

-Blood cells are the important elements of the blood.

-There is the different type of blood cells in blood. Blood contains the three types of blood cells. Blood cells are the formed by the specified organs.

-Blood cells are produced by the born marrow. Born marrow is the soft fatty tissue inside bone cavities. 

-And process of blood formation is known as hematopoiesis. 

- Following are the types of blood cells

1.    Red blood cell (erythrocytes)

2.    White blood cell (Leukocyte)

3.    Platelets  (Thrombocyte )

Red blood cells

-Red blood cells approximately 40 to 45 percent of the blood. The life of red blood cells is 120 days. Red blood cells transport oxygen to the different cells of the body.

White blood cells

-White white blood cells approximately 1 % of the blood cells.  The life of white blood cells is around 6 hour only. White blood cells are the reason for our immune system White blood cells are fighting with infections.

Platelets            

Platelets are the small blood cells present into the blood. Average platelet count is 150,000 to 450,000 platelets per microliter of blood.

-Platelets help blood to clot and Platelets are rapidly deployed to sites of injury or infection.
