Question

a. Microorganisms such as yeast and some other bacteria respire anaerobically. What do you understand by

the term anaerobic?


b. Identify the type of respiration from its word equation and define the process.

Glucose + Oxygen Carbon dioxide + water + Energy (38 ATP)​

Answer 1

Answer:

(a).

• Anaerobic respiration is a type of respiration that does not require Oxygen to synthesis ATP(adenosine triphosphate).
• Here, comparatively less ATP is produced than aerobic respiration. (2 ATP)
• Anaerobic respiration forms either Alcohol or Lactic Acid as biproducts.
• Eg.: Clostridium, Yeast, etc.

(b).

• This is Aerobic respiration.

Here, the End products of sugars from digestion are taken from the small intestine and mixed with the blood stream, this is taken to every single cell in the body where the Glucose(C6H12O6) is oxidised and Energy is produced.

There are four steps involved in this process,

• glycolysis,
• the citric acid (Krebs) cycle,
• an electron transport chain and.
• chemiosmosis.

This process gives out 38 ATP molecules.

Answer 2

A: anerobic means self respiration
B:anerobic respiration
