Q

explain how this feedback mechanism conserves the cells resources

A

this ensures that glucose is only used when required

17
Q

diagram X , Y, Z

A

X= amino acids
Y= fats
Z= Co2

18
Q

what term describes the breakdown of carbohydrate into pyruvate during respiration

A

Glycolysis

19
Q

describe what happens to acetyl coenzyme A during respiration

A

acetyl combines with oxaloacetate acid to become citrate

20
Q

when might the body obtain most of its energy from proteins?

A

when the body has used up all carbohydrate and fats

21
Q

where is carbohydrate form stored and the location

A

> glycogen
muscles
