What is the four main steps of cellular respiration?

Answer 1

There are four main steps in cellular respiration are glycolysis, Link Reaction, Krebs Cycle and Hydrogen Transport Chain.

In glycolysis, glucose molecules are broken down into pyruvate and pyruvic acid. Two molecules of ATP are produced in this cycle. This is fed into a link reaction, where some chemical rearrangement occurs.

The Krebs cycle, also called the Citric acid cycle, allows extensive rearrangement of the atoms to occur. 2 molecules of ATP are produced in this cycle, bringing the total to four so far. Carbon dioxide is released as a byproduct, while the hydrogen atom is passed on to the next cycle.

The hydrogen transport chain, also called the electron transport chain, is the last step of cellular respiration. In this phase, the electron belonging to the hydrogen is passed along a chain of receptors, with oxygen as the final receptor. The hydrogen atom is not used up in the reaction. This step provides the most ATP, with 32 molecules being produced.

Answer 2

The four stages are glycolysis, oxidation of pyruvate, the Krebs cycle, and the electron transport chain.

Answer 3

The four stages are : 1) Glycolysis 2) Formation of acetyle CoA (in the mitochondria) 3) Citric acid cycle (in mitochondria) 4) Electron transport and chemiosmosis (in mitochondria)

Answer 4

glycolysis,krebs cycle,electron transport chain

Answer 5

Generally, there are only three main phases of cellular respiration. These phases are glycolysis, Krebs cycle or citric acid cycle and the electron transport chain.

Answer 6

• Glycolysis (the break down of glucose)
• Link reaction.
• Krebs cycle.
• Electron transport chain, or ETC
