Question

G If we (humans) do not have enough oxygen to allow aerobic respiration to occur, what will happen? Group of answer choices

Answer 1

Answer:

We will produce lactate/lactic acid through fermentation.

Explanation:

During strenuous activities, muscle cells do not sufficient supply of oxygen to meet the energy requirements. As a result, anaerobic respiration occurs to temporarily supply energy and lactic acid is produced instead of carbondioxide and water.

Lactic acid accumulates in muscles and eventually preventing further contraction. The muscle cells are said to have incurred an 'oxygen dept' since they have used up more energy than was possible from the oxygen supplied to them. The largest amount of lactic acid a body of a trained athlete can tolerate is about 127grams, and the largest tolerable oxygen is about 16 litres.

Answer 2

Answer:

1) We will produce lactate/lactic acid through fermentation

2) We will produce alcohol through fermentation

Explanation:

Under anaerobic conditions I.e the absence of oxygen, pyruvic acid enters through any of this three pathways:

1) lactic acid fermentation

2) alcohol fermentation, or

3) cellular (anaerobic) respiration.

All these pathways can also lead to the production of ATP.
