What is the second step in aerobic respiration?

The second step in aerobic respiration is the formation of acetyl coenzyme A. In this process, pyruvate is oxidized in the mitochondria and 2-carbon acetyl group is produced.

Which is the second step of cellular respiration?

The second stage of cellular respiration, called the Krebs cycle , takes place in the matrix of a mitochondrion.

What are the 2 aerobic stages of cellular respiration?

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

What are the 3 steps in aerobic cellular respiration?

Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain. Glycolysis: Glucose ( 6 carbon atoms) is split into 2 molecules of glyceraldehyde phosphate (3 carbon each), then these are turned into pyruvate (3 carbons each).

What is the second step in aerobic respiration quizlet?

The second stage of aerobic respiration includes glycolysis and the Krebs cycle. All food must be broken down to glucose before ATP can be produced. The true energy payoff for aerobic respiration occurs during electron transfer phosphorylation.

What are the 5 stages of aerobic respiration?

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.

What is the 1 step in anaerobic respiration?

The first step of anaerobic respiration is glycolysis, in which a glucose molecule is broken down into two pyruvate molecules, releasing electrons in the process and producing two ATP molecules, the energy of the cells.

What happens to the electrons in the second stage of aerobic respiration?

1. In this step electron transfer chains put electrons and hydrogen atoms from glucose to use. 2. NADH and FADH2 donate their electrons to transfer (enzyme) systems embedded in the inner mitochondrial membrane.
