Question

Describe in detail how glucose is broken down in the presence of oxygen and without oxygen

Answer 1

Answer:

In presence of oxygen :: Aerobic Respiration

Glucose is completely break down into pyruvate (a three carbon molecules). More energy is produced

In absence of oxygen :: Anaerobic Respiration

Glucose is incompletely break down into lactic acid but less energy is produced and cause muscle cramps

Answer 2

Answer: When glucose break down in the presence of oxygen it is aerobic respiration and when it breaks down in the lack of of oxygen it is anaerobic respiration

Explanation:

Presence of oxygen: it occurs in mitochondria glucose break down giving end products carbon dioxide+ water + enery

Lack of oxygen : it occurs in muscle cell and give end products lactic acid + enery

In absence of oxygen : it occurs in yeast and result into ehanol + carbon dioxide + enery
