42g

Question 8

Question 10

What four ways can glucose be metabolised?

Answer 10

1. oxidative metabolism in tissues
2. glycogen synthesis and storage in skeletal muscle and liver
3. pentose phosphate pathway (produce DNA and RNA)
4. Lipogenesis in the liver and adipose tissue for energy storage as triglycerides (ruminants don’t convert glucose to long chain fatty acids)

Question 11

What is the effect of insulin and is it catabolic or anabolic?

Answer 11

anabolic. reduces glucose and free fatty acids in circulation

Question 12

What is the effect of glucagon and is it catabolic or anabolic?

Answer 12

catabolic. increases glucose and free fatty acids in circulation

Question 13

What areas have the highest requirements for glucose?

Answer 13

The CNS, developing foetus and mammary glands
