Gene expression - chuck 3

Question 1

metabolic pathway

Answer 1

a series of enzyme controlled reactions, where the product of one reaction is the reactant in the next reaction.

Question 2

substrate

Answer 2

the molecule that an enzyme acts on. it has a specific shape that fits the enzyme

Question 3

enzyme

Answer 3

are biological catalysts that lower the activation energy needed to start a reaction by providing an alternative reaction pathway

Question 4

metabolism

Answer 4

sum of all the enzyme-controlled reactions that occur in a cell

Question 5

how mutation works in a gene and how does it effect enzymes

Answer 5

If only gene A is mutated, this means enzyme A is not functional/not made. If enzyme A does not work, it means that the substrate will not be converted to the end product and will accumulate,
