Diffusion, Osmosis and Enzymes
The diffusion of water from a high concentration to a low concentration
Lowers the amount of energy needed to perform chemical reactions
When you breath O2 passes into your blood stream while CO2 passes out of your blood stream
Involved with, but does not become a part of chemical reactions
Small molecules with no charge can move through semi-permeable membranes by this process
a. Enzymes
b. Simple Diffusion
c. Enzymes
d. Simple Diffusion
e. Osmosis

These are to match up

The given statements can be matched as following:

a)The diffusion of water from a high concentration to a low concentration  - Osmosis

b)Lowers the amount of energy needed to perform chemical reactions - Enzymes

c)When you breath O2 passes into your blood stream while CO2 passes out of your blood stream -Simple Diffusion

d)Involved with, but does not become a part of chemical reactions -Enzymes

e)Small molecules with no charge can move through semi-permeable membranes by this process- Simple Diffusion

Explanation:

a) Osmosis is generally defined as the process by which water is transported from a region of Higher concentration to the region of Lower concentration.

b) Enzymes are well known to reduce the amount of energy required or needed for a chemical reaction to take place.

c)The process by which oxygen passes through our blood stream and carbondioxide passes through the other is known as simple diffusion process.

d) Enzymes are ones that actively gets involved in the chemical reaction but they will never become a part of that chemical reaction.

e) Diffusion is the process by which very small molecules that carries no charge moves through semi permeable membrane.
