Respiration in Muscles

Q. A sprinter experiences muscle cramps in his legs due to the lack of oxygen in muscles. This is due to the conversion of pyruvate to:

1. Acetic acid
2. Carbon dioxide
3. Lactic Acid
4. Ethanol

Q.

The diagram below represents the breakdown of glucose by various pathways. Choose the correct option.
.

1. (i) - In cytoplasm, (ii) – Energy, (iii) – Carbon dioxide, (iv) – Water, (v) – Lactic Acid, (vi) – Absence of oxygen,
   (vii) – In yeast, (viii) – Ethanol.

2. i) - In mitochodria, (ii) – Water, (iii) – Oxygen, (iv) – Carbon dioxide, (v) – Lactic Acid, (vi) – Absence of oxygen, (vii) – In cytoplasm, (viii) – Lactic Acid.

3. i) - In cytoplasm, (ii) – Water, (iii) – Carbon dioxide, (iv) – Energy, (v) – Lactic Acid, (vi) – Presence of oxygen, (vii) – In ameoba, (viii) – Pyruvate

4. i) - In human cells, (ii) – Energy, (iii) – Carbon dioxide, (iv) – Energy, (v) – Lactic Acid, (vi) – Absence of carbon dioxide, (vii) – In yeast, (viii) – Ethanol.

Q. What is lactic acid? Explain.

Q.

Explain:
Type of respiration in which the end product is lactic acid.

Q. Anaerobic respiration is

1. When breakdown of glucose occurs with the use of oxygen is called anaerobic respiration.
2. When breakdown of glucose occurs with the use of nitrogen and oxygen is called anaerobic respiration.
3. When breakdown of glucose occurs with the use of carbondioxide and oxygen is called anaerobic respiration.
4. The food can also be broken down, without using oxygen is called anaerobic respiration.
