Question

Which pathway is common to both aerobic and anaerobic respiration?

• A. Electron transport chain
• B. Glycolysis
• C. Kreb's cycle
• D. Calvin cycle

Answer 1

The correct option is B Glycolysis

$\bullet$ In simple words, glycolysis is the process where sugar or glucose is broken down to get energy.
$\bullet$ The glucose molecule is converted into pyruvic acid through glycolysis. The site of glycolysis is the cytoplasm of the cell.
$\bullet$ Glycolysis is the initial step that is similar in aerobic and anaerobic respiration; hence it is called the common pathway.
$\bullet$ The resulting pyruvate molecule is used in both types of respiration to either convert into acid or alcohol (Anaerobic) or produce carbon dioxide or water molecules (aerobic).
