AEROBIC RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the correct order of processes in Aerobic Respiration?
A
Glycolysis, Chemiosmosis, Kreb’s Cycle, Electron Transport Chain
B
Glycolysis, Chemiosmosis, Electron Transport Chain, Kreb’s Cycle
C
Chemiosmosis, Electron Transport Chain, Kreb’s Cycle, Glycolysis
D
Glycolysis, Kreb’s Cycle, Electron Transport Chain, Chemiosmosis
Explanation: 

Detailed explanation-1: -So, the correct answer is ‘Glycolysis, Krebs cycle, Electron transport chain’.

Detailed explanation-2: -FADH2: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain. Glycolysis is the first of the three steps used to breakdown glucose to produce ATP. Glucose, a 6 carbon sugar, is split into two 3 carbon sugars.

Detailed explanation-3: -There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation.

Detailed explanation-4: -The three stages of aerobic cellular respiration are glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation.

Detailed explanation-5: -In order for aerobic respiration to occur, the 5 stages that have to take place are glycolysis, oxidation of pyruvate, Krebs’s cycle, electron transport chain, and chemiosmosis (Notes, 10/5/15). Glycolysis is the splitting down of the sugar molecules into 2 3-carbon molecules.
