UNIT 2: key area 1 a) metabolic pathways

Question 1

define term metabolism

Answer 1

metabolism is all of the reactions that take place inside living cells

Question 2

describe what is ment by a metabolic pathway

Answer 2

a series of chemical reactions that start with a substrate and finish with an end product

integrated and controlled enzyme catalysed reaction in a cell

Question 3

what is a anabolic reaction

Answer 3

anabolic reaction build up large molecules from smaller ones
they require energy to do so

Question 4

what is a catabolic reaction

Answer 4

catabolic reactions break down large molecules into smaller ones

they release energy by doing so

Question 5

compare anabolic and catabolic pathways

Answer 5

anabolic builds up large molecules and require energy whereas catabolic break down large molecules by releasing energy
