1.
Glucose and amino acids absorbed into the villi enter the:
Blood capillaries
Stomach
Liver directly without blood
Lacteal only
2.
Which hormone lowers blood glucose?
Insulin
Glucagon
Testosterone
Adrenaline
3.
Insulin lowers blood glucose by
stopping digestion
causing cells to take up glucose and the liver to store it as glycogen
breaking down glycogen
increasing glucose release from the liver
4.
Cotransport of glucose with sodium ions relies on
a sodium gradient built by active transport
simple diffusion through the bilayer
exocytosis
glucose moving down its own gradient only
5.
Blood glucose rises after a meal. Insulin is released and glucose falls. This is an example of
negative feedback
positive feedback
apoptosis
signal amplification

A student described the formation and elimination of urine as follows. In which step is the error? Step 1: Blood is filtered from the glomerulus into Bowman's capsule. Step 2: The filtrate passes through the renal tubule, where water and glucose are reabsorbed. Step 3: Urine collects in the collecting duct and then the ureter. Step 4: Urine moves from the ureter to the urethra and is then stored in the bladder.
