Quiz Answer Key and Fun Facts

1. Which of these actions cannot be said to be an effect of insulin?

Answer: Stimulates the convertion of glycogen into glucose

Insulin is produced in the pancreas in the islets of Langerhans.
The word insulin comes from the Latin "insula", meaning island.

2. Which of these enzymes can be found in saliva?

Answer: Amylase

Amylase begins the breakdown of starches into sugars. It is responsible for the sweet taste of starchy foods after excessive chewing.
Exopeptidases and endopeptidases are involved in the breakdown of proteins into amino acids.
Maltase can be found the the cell membrane of of epithelial cells of the small intestine and breaks down maltose into glucose.

3. Lymph capillaries are involved in the drainage of what?

Answer: Excess tissue fluid

If there is damage to lymph capillaries, there is often swelling in certain body parts due to the accumulation of excess tissue fluid.

4. After undergoing ultrafiltration and selective reabsorption, this fluid passes out of the body via the urethra.

Answer: Urine

During ultrafiltration, the blood is under pressure and so water glucose and other small molecules are forced out into the capsular space. Larger molecules such as blood cells remain in the capillaries.
During selective reabsorption, all of the glucose is reabsorbed into the blood. Also, some water, ions and urea passively move back into the blood.

5. Humans cannot store excess amino acids and so they must be converted into what substance?

Answer: Urea

Amino acids are firstly oxidised into ammonia, which then enters the "Ornithine Cycle" where it is rapidly converted into urea.

6. What are the usual products when lipids are broken down in the human body by lipase?

Answer: Fatty acids and Glycerol

Other products can include monoglycerides and diglycerides. These are produced when the triglycerides which make up lipids are not completely broken down.
Glucose and maltose are both sugars produced during the breakdown of starch.
Folic acid is also known as vitamin B8/B9/M.

7. Impulses are passed from one neurone to the next across a synapse via a neurotransmitter. What is the neurotransmitter found in adrenergic synapses?

Answer: Nor-Adrenaline

Both sodium and calcium ions are involved in the propagation of impulses along a neurone and the contraction of muscles.
Nor-Adrenaline is involved with the sympathetic nervous system, which is activated at time of stress or excitement.

8. This substance is present in several parts of the body. It is present in the stomach and its function is to prevent damage to the stomach walls by acid erosion.

Answer: Mucus

The stomach contains three types of muscles in its walls in order to churn food before it leaves to be digested further in the small intestine. These muscles are known as longitudinal, circular and oblique.

9. ADH is secreted by which endocrine gland?

Answer: Pituitary gland

ADH stands for Anti-Diuretic Hormone. It causes the kidneys to reabsorb water from the kidney filtrate which would otherwise pass out as urine.

10. Proteins are made up of monomers called amino acids. Which element is not always present in amino acids?

Answer: Sulphur

Some amino acids do contain sulphur. However, ALL amino must contain carbon, oxygen, hydrogen and nitrogen.
Amino acids are made up of the acidic carboxyl group and the basic amino group.
