Biochemical pathways

Question 1

activation energy

Answer 1

the energy required to initiate a reaction

Question 2

ATP

Answer 2

adenosine triphosphate, a high energy molecule that, when broken down, provides energy for cellular processes

Question 3

catalyst

Answer 3

a substance capable of increasing the rate of a reaction without being used up

Question 4

active site

Answer 4

the part of an enzyme where the substrate binds

Question 5

anabolic

Answer 5

build larger molecules out of smaller molecules or atom

Question 6

coenzyme

Answer 6

a non-protein organic cofactor that assists enzyme function. They release energy and are recycled during a reaction

Question 7

enzyme

Answer 7

an organic molecule, typically a protein, that catalyses (speeds up) specific reactions

Question 8

irreversible inhibitor

Answer 8

enzyme inhibition that involves stronger bonds that cannot be broken

Question 9

Catabolic

Answer 9

break down large, complex molecules into smaller, simple ones.

Question 10

cofactor

Answer 10

any organic or inorganic molecule, such as a coenzyme or metal ion, that assists enzyme function

Question 11

reversible inhibitor

Answer 11

enzyme inhibition that involves weaker bonds that can be overcome

Question 12

substrate

Answer 12

the reactant of a reaction catalysed by an enzyme
