Internal membranes and enzymes

Question 1

Describe the structure and role of the active site of an enzyme

Answer 1

Structure- The active site consists of amino acid residues that form temporary bonds with the substrate, the binding site, and residues that catalyse a reaction of that substrate, the catalytic site.
Role- Bind other small molecules that participate in catalysis

Question 2

Biochemical processes are controlled and regulated by…

Answer 2

a series of specific enzymes

Question 3

What factors affect reaction rates of enzymes (T,P,I, CRP)

Answer 3

temperature
pH
the presence of inhibitors
the concentrations of reactants and products

Question 4

How does the arrangement of internal membranes control biochemical processes

Answer 4

The folding of the inner membrane increases the surface area inside the organelle. Since many of the chemical reactions happen on the inner membrane, the increased surface area creates more space for reactions to occur
