Question

In aerobic respiration
A) Glucose is the only substrate
B) Glucose is a preferred substrate
C) Glucose cannot be used directly
D) Any material which burns in air can be used as substrate

Answer 1

glucose cannot be used directly to produce energy

Answer 2

The answer is option B

Glucose is a preferred substrate.

• Respiration is the process by which the respiratory substrate will break down to release energy.
• Aerobic respiration is a chemical process by which oxygen is used to make energy from carbohydrates (sugars). Also called aerobic metabolism, cell respiration, and oxidative metabolism.
• The two main working elements of cell respiration are aerobic and anaerobic respiration, where aerobic respiration needs the presence of oxygen and anaerobic respiration does not.

• A respiratory substrate is a fragment(molecule) that gets oxidized during respiration

• The most common respiratory medium in the body is glucose.  One molecule of glucose gives 38 molecules of ATP, making it an instant source of energy.

• The most common respiratory medium is glucose, which has a 6-carbon compound.
• The substrate is metabolized through glycolysis, the TCA cycle, electron transport chain, and oxidative phosphorylation.
• Aerobic respiration is the process by which the energy is obtained by breaking down the complex molecule into simpler ones in the presence of oxygen.
• Glucose is the substrate that joins the process from glycolysis and protein and fat are able to join it from Kreb's cycle.
