Reverse osmosis definition

Reverse osmosis definition:

Definition:

Reverse Osmosis is defined as the movement of solvent in the opposite direction from the osmosis; when pressure is applied.
Pressure is most important factor in reverse osmosis process.

Diagram of Reverse Osmosis:

Reverse Osmosis

-Here is a diagram, the red molecules are the molecule of the solvent while the blue is the solute molecule. And the dotted line is the semipermeable membrane. Pressure is applied to the side where the concentration of the solute is high.

-Due to the applied pressure, thee red solvent molecule passes through the semipermeable membrane toward the other side where the concentration of solute (Blue color molecule) is low. This phenomenon is known as Reverse Osmosis.

Osmotic pressure Definition

Osmotic pressure Definition:

Osmotic pressure defined as the Maximum pressure developed in osmotic process.

Osmotic pressure is the pressure required to prevent the movement of the water across the semipermeable membrane

Potential osmotic pressure Definition :

Potential osmotic pressure defined as the maximum osmotic pressure that develops in a solution when separated from its pure solvent by a semipermeable membrane.

Difference between Blood and Plasma

Blood and plasma are the two different elements. Plasma is the component of the blood. Plasma is approximately % of the blood complement. There are so many differences between blood and Plasma.

Following are the difference between Blood and Plasma

	Blood	Plasma
Definition	Blood is the fluid in our body which transport nutrient and the oxygen to the different cell of the body.	Plasma is the yellow colour fluid; left after removal of blood cells which constitutes 55% of blood part.
Component	Blood is composed of plasma, blood cells(red blood, White blood, and platelets)	Plasma composed of the water, protein, nutrient, electrolyte, and gases.
Colour	Red Colour fluid	Light yellow colour liquid
Donation	Blood donation is very common	Plasma donation is less common.
Treatment	Blood is directly collected from the vein.	For Plasma collection special machine and treatment are required.

Definition of crystal Habit

Definition of crystal Habit:

-A crystal habit is defined as the description of the outer appearance of a crystal whereas the internal structure is the molecular arrangement within the solid.

-Any crystal is characterized by its internal structure and habit.

-Crystal habit can also be modified by adding impurities or ‘poisons’; for example, sulphonic acid dyes alter the crystal habit of ammonium, sodium and potassium nitrates.

-It can be quantitatively expressed in terms of aspect ratio (AR), defined as the ratio of length to width and values of AR approaching 1 (spherical or cube shape) are considered to be pharmaceutically good. It is preferable to keep the AR values below 5 so as to avoid problems with flow. AR in polar solvents was as high as 9.4 in comparisons with 5-6 in non-polar solvents.

Simple diffusion vs Facilitated diffusion

simple diffusion vs facilitated diffusion

Diffusion mean the movement of the molecules from higher concentration to lower concentration Based on presence of facilitator it categorise as the Simple diffusion and the Facilitated diffusion. There is difference between the simple and the facilitated diffusion.

	Simple diffusion	Facilitated diffusion
requirement	Simple diffusion occur without the any aid of the facilitate molecule (Chanel protein or carrier protein)	Facilitated diffusion requires the Facilitate molecule to happen the diffusion,.
Rate	Simple diffusion is relatively slow than the facilitated diffusion.	Facilitated diffusion is relatively faster than the simple diffusion
Type	Simple diffusion is a passive activity.	Facilitated diffusion is may be active or the passive its depends.
Energy	Simple diffusion does not require the energy	Facilitated diffusion may require or not require the energy.
Type of particle	Simple diffusion transports small particles and non polar molecular.	Facilitated diffusion transport the large molecule and the polar molecule.

Enzyme: Definition and structure

Definition:

- Enzyme is defined as the chemical substance which produces into the living cell and acts as the catalyst into the body.

-Enzyme is the catalyze the chemical reaction. Enzyme increase the rate of reaction occurs in our body.

- Most of the enzyme is the protein molecule.

-The name of the any enzyme generally suffix as “ase”.

Structure of the Enzyme

- Generally, an enzyme is the protein molecule. The sequence of the amino acid available in enzyme specifies the structure which in turn determines the catalytic activity of the enzyme.

- Some enzyme the two part. The protein part of the enzyme knows as the apoenzyme and the non protein part of the enzyme known as the Coenzyme or cofactor.

- When the non protein part of the enzyme is metal ion (ion, magnesium zinc etc.) that non protein part is known as the co-enzyme.

- When non protein part of the enzyme is vitamin or derived from the vitamin, that non protein part is known as the co-factor.

Definition of Hormone

Definition of Hormone:

Hormone is defined as the chemical substance which produces by the endocrine gland which regulates and controls the different function of the body.

Properties of Hormones:

-Hormones are the secreted by the endocrine gland and diffuse into the blood.

-Hormones are the chemical messenger and hormones may be classified as water soluble hormone and the lipid soluble hormones.

-Hormone act on the specific target cells only. The target cells have receptor. Hormones bind with that receptor.

-Hormone Receptor Interaction is Reversible.

-The binding of hormone to receptor is a saturable process.

- Many hormones are produced in their inactive form which is known as the pro hormone.

Difference between hydrophilic and Hydrophobic

Hydrophilic and hydrophobic are the two terms used. Hydrophilic mean water loving and hydrophobic mean water replant.

Following are the difference between Hydrophilic and Hydrophobic Molecule.

	Hydrophilic	Hydrophobic
Definition	Hydrophilic means which attract the water	Hydrophobic mean which repeals the water
Polarity	Hydrophilic molecules are polar	Hydrophobic molecules are nonpolar.
Example	water, cellulose etc	Wax, Oil, fatty acid
Dissolution	Hydrophilic molecule is dissolved in water	Hydrophobic molecule does not dissolve in water.
