Metabolism

Question 1

Skeletal muscle requirement

Answer 1

Light contraction met by oxphosp
Vigorous glycogen breakdown
Lactate form

Question 2

Excess g 6 p and fatty acid

Answer 2

G6p to glycogen

Excess acetyl coa to fatty acids

Question 3

When fasting what happens to acetyl coa

Answer 3

Instead of entering tca it results in Ketone bodies

Question 4

What does the body do to avoid hypoglycaemia

Answer 4

Glycogenlysis
Release fatty acids from adipose tissue
Convert acetyl coa to ketone bodies in liver

Question 5

Why ketone bodies

Answer 5

Ketone bodies and fatty acids

Used by muscle and Heart allowing more glucose for brain

Question 6

The 3 irreversible reactions catalyst

Answer 6

Hexokinase
Phosphofrucyokinase
Pyruvate kinase

Theses are bypassed in gluconeogeniss

Question 7

What are glucogenic amino acids

Answer 7

Their skeletons give rise to glucose via gluconeogenis

Question 8

Ketogenic aa give rise to

Answer 8

Sketeltons which can’t enter gluconeogenisis but synthesis fatty acids and ketone bodies

Question 9

Increase in demand of glucose is met how in the muscle

Answer 9

Increase number of glucose transporters on membranes of muscle cells

Question 10

G 6 phosphatase

Answer 10

Catalysed the reverse reaction to get glucose form g 6 p

Question 11

Glucocorticoid

Answer 11

Steroids hormone increase synthesis of metabolic enzymes cornered with glucose enzymes

Question 12

Secraetionof insulin

Answer 12

Increase glucose uptake by liver and muscle
Increase glycogen synthesise
Increase triglyceride suthesis in adipose
