Anaerobic Respiration

Q.

Why do we sometimes suffer from muscle cramps while exercising?

Q.

The product of anaerobic respiration of yeasts is:

1. Oxygen

2. Lactic acid

3. Carbon dioxide

4. Alcohol

Q. Our muscles get muscle cramp because our muscles can respire anaerobically, resulting in the formation of lactic acid. How does this lactic acid help? How?

Q.

Respiration in the absence of oxygen is called __ respiration.

Q. Sometimes when we do heavy exercise, anaerobic respiration takes place in our muscle cells. What is produced during this process?

1. alcohol and lactic acid
2. alcohol and $C{O}_2$
3. lactic acid and $C{O}_2$
4. lactic acid only

Q.

What is the type of respiration performed by marathon runners during most of their run?

3. Anaerobic respiration

4. Aerobic respiration

Q.

Why is anaerobic respiration bad?

Q.

Question 2
Yeast is used in wine and beer industries because it respires

(a) aerobically producing oxygen
(b) aerobically producing alcohol
(c) anaerobically producing alcohol
(d) anaerobically producing $C{O}_2$

Q.

Why is it difficult to calculate the respiratory quotient in plants?
