举一反三
- Which of the following description about islet hormones is correct? A: Pancreatic alpha cells produce glucagon B: Pancreatic beta cells produce insulin with low glucose C: Somatostatin produced by pancreatic delta cells enhances insulin secretion D: Somatostatin produced by pancreatic delta cells enhances glucagon secretion E: Insulin can pass through the plasma membrane
- Which of the following is least likely to be associated with an increase in the inflammatory <br/>response? A: necrosis of cells, followed by phagocytosis of neutrophils B: release of peptides curing cleavage of fibrinogen to fibrin (blood clotting) C: cleavage of C5 during complement activation D: apoptosis of surplus healthy cells E: secretion of IFNγ by macrophages and TH cells
- Among those hormones, which secretion will increase following a meal? ( ) A: adrenalin B: glucagon C: insulin D: glucocorticoid E: growth hormone
- According to the video, which of the following is wrong A: Insulin binds to specific receptors and acts like a key to open a pathway for glucose to enter the cell. B: Type 2 diabetes is caused by insufficient insulin or insulin resistance or both. C: When blood sugar rises, islet A cells sense it and release insulin to regulate blood sugar. D: When cells can't use glucose, they break down fats and proteins, producing ketones.
- i) The secretion of insulin—which acts to lower the plasma glucose _____—is stimulated by a rise in glucose concentration, for example, and is inhibited by a fall in blood glucose.
