Explanation / Answer

50.

Cholecystokinin is an intestinal hormone that stimulates the gallbladder to contract and release stored bile into the intestine.

51.

An intestinal hormone that stimulates the release of insulin from the pancreatic islet cells is the Gastric inhibitory peptide (GIP).

52.

The Kupffer cells of the liver destroy RBC, present antigens, destroy bacteria and are phagocytic.

53.

Functions of the liver

bile production, hematological regulation, metabolic regulation, albumin production for blood osmotic pressure regulation.

54.

In response to the hormone secretin, the pancreas secretes a fluid rich in bicarbonate ion.

55.

Hydrochloric acid from the stomach is neutralized in the small intestine by sodium bicarbonate from the pancreas.

56.

Pancreatic juice contains enzymes that breakdown carbohydrates, lipids and proteins.

57.

Trypsin is a protease

58.

In oxidative phosphorylation, energy for the synthesis of ATP is directly obtained from the movement of hydrogen ions through channels in the inner mitochondrial membrane

59.

When NAD+ is reduced, it becomes NADH. When NADH is oxidised, it becomes NAD+.

60.

Most of the ATP from metabolism is produced in the Electron transport system.
