Question

Glucose is broken down in the chemical processes of aerobic respiration.

Answer 1

$\bold{\huge{\purple{\underline{ Answer }}}}$

Aerobic respiration :- Aerobic respiration is process of respiration in which complete oxidation of glucose takes place in the presence of oxygen

That is,

Aerobic respiration is takes place in four stages :-

• Glycolysis
• The link reaction
• The Krebs cycle
• Oxidative phosphorylation

In aerobic respiration, Glucose with 6 carbon atoms broken into 2 pyruvic acid each with 3 carbon atom and produces water + CO2 + energy.

Whereas,

Anaerobic respiration :- is the process of respiration in which incomplete oxidation of glucose takes place in the absence of oxygen

The end products of glucose in anaerobic respiration is

• In human muscles, Lactic acid + Energy
• In yeast, Ethanol + CO2 + Energy

Hence, Option D is the correct answer.
