Gaseous exchange and respiration questions | form two Biology

A biologist collected blood samples from an athlete at intervals to determine the amount
of lactic acid accumulation. The following were the results obtained.

Study above and answer the following questions.

(i) Name the process which leads to the accumulation of lactic acid.
(ii) In which animal tissue is lactic acid formed?
(iii) What are the effects of accumulation of lactic acid in the body?

(iv) From the results shown in Table 1 above, which range of time represents the
period of recovery?
(v) Write a word equation for anaerobic fermentation in plants.

Inhaled air has high content of oxygen.

The product of anaerobic respiration process in animals is
A uric acid
B lactic acid
C sulfuric acid
D hydrochloric acid.

It is safe to warm the room by using charcoal when people are sleeping the whole night inside the room.

Gaseous exchange in fish takes place through the spiracles.

Muscle fatigue in the body is caused by:
A. lack of carbon dioxide
B. lack of lactic acid
C. lack of oxygen
D. pyruvic acid

(a) What do you understand by the term “diffusion”?
(b) Name two structures concerned with gaseous exchange in plants.
(c) Explain the importance of gaseous exchange in plants.

(b) What is respiration?
(c) Differentiate between aerobic and anaerobic respiration.

Oxygen passing from the atmosphere into the blood of a mammal takes one of the following routes

1. bronchi- brochioles-trachea-alveoli
2. trachea- brochioles-bronchi-alveoli
3. trachea-brochi-brochioles-alveoli
4. brochioles-brochi-trachea-alveoli
