17. Glucagon can increase blood glucose levels.

Answer 1

12 - A

Major organs of gluconeogenesis are liver (mostly) and kidney.

13- B

Acetone is not used as energetic source . Rest both are used as fuel by cells.

14 - true

Transamination process happens both in cytosol and matrix of mitochondria.

15- B (malate)

16- B

Preferred order of nutrients to be digested by body is carbohydrates - fatty acids/lipids - proteins.

17- true.

Insulin controls the amount of sugar in bloodstream. In cases like fasting low level of glucose is raised by glucagon, so that glycogen is converted into glucose back.
