CELL RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are the three stages that make up cellular respiration?(Accelerated you learned 4 stages)
A
light reactions, Calvin cycle (dark reactions) and electron transport
B
glycolysis, Kreb’s cycle and Calvin cycle (dark reactions)
C
Glycolysis, Kreb’s cycle and electron transport
D
Light Reactions, Calvin Cycle (dark reactions) and Glycolysis
Explanation: 

Detailed explanation-1: -Thus the correct order of the stages in cellular respiration is: Glycolysis-Oxidative decarboxylation-Krebs cycle-Electron transport chain-Oxidative phosphorylation .

Detailed explanation-2: -There are three main steps of cellular respiration: glycolysis; the citric acid (TCA) or the Krebs cycle; and the electron transport chain, where oxidative phosphorylation occurs. The TCA cycle and oxidative phosphorylation require oxygen, while glycolysis can occur in anaerobic conditions.

Detailed explanation-3: -The overall process, however, can be distilled into three main metabolic stages or steps: glycolysis, the tricarboxylic acid cycle (TCA cycle), and oxidative phosphorylation (respiratory-chain phosphorylation).

Detailed explanation-4: -The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

Detailed explanation-5: -In eukaryotes, the 4 stages of cellular respiration include glycolysis, transition reaction (pyruvate oxidation), the Krebs cycle (also known as the citric acid cycle), and oxidative phosphorylation through the electron transport chain.
