In cellular respiration, ATP is primarily produced during two steps: glycolysis and oxidative phosphorylation. Glycolysis, which occurs in the cytoplasm, generates a net gain of 2 ATP molecules. The majority of ATP, however, is produced during oxidative phosphorylation in the mitochondria, where the electron transport chain and chemiosmosis yield approximately 28-34 ATP molecules, depending on the cell's efficiency. The Krebs cycle also contributes indirectly by generating electron carriers that feed into oxidative phosphorylation.
What else can I help you with?
Which of the steps of cellular respiration requires the use of two ATP and yields four ATP?
Glycolosis uses two ATP to release the energy, creating four ATP.
What are the four steps to aerobic cellular respiration?
The four stages of aerobic cellular respiration are:GlycolisisLink ReactionKrebs CycleElectron Transport ChainEach step is important and cannot happen without the one before it.
What is the main fuel for cellular respiration?
the main fuel for cellular respiration is protein, fat, sugar, and oxygen from the food you eat.
How many organisms need to be in a food chain to carry out cellular respiration?
Every organism in a food chain carries out cellular respiration. It involves the breakdown of organic molecules to release energy for metabolism. So, at least one organism in a food chain is needed to carry out cellular respiration.
What 4 products are produced by the cell during cellular respiration?
The four main products produced by the cell during cellular respiration are ATP (adenosine triphosphate), carbon dioxide (CO2), water (H2O), and heat. These products are essential for providing energy for cellular processes and maintaining metabolic functions in the body.

Identify four components of respiration?
The four components of respiration are ventilation (breathing), gas exchange (in the lungs and tissues), transport of gases (via the bloodstream), and cellular respiration (generation of ATP in cells).
What is the four main steps of cellular respiration?
The four main steps of cellular respiration are glycolysis, pyruvate oxidation, the citric acid cycle (Krebs cycle), and oxidative phosphorylation (electron transport chain and chemiosmosis). These steps occur in different parts of the cell and result in the production of ATP for cellular energy.
4 phases in aerobic cellular respiration?
The four phases of aerobic cellular respiration are glycolysis, pyruvate oxidation, the citric acid cycle (also known as the Krebs cycle), and oxidative phosphorylation (including the electron transport chain and chemiosmosis). These phases collectively break down glucose to produce ATP, the cell's main energy currency, in the presence of oxygen.
In cellular respiration a two carbon molecule combines with a four carbon with four carbon molecules to form citric acid as part of?
In cellular respiration, a two-carbon molecule (acetyl-CoA) combines with a four-carbon molecule (oxaloacetate) to form citric acid in the first step of the citric acid cycle (Krebs cycle). This process occurs in the mitochondria and is essential for the production of ATP through the oxidation of acetyl-CoA.
ATP is produced during cellular respiration However it is also required Explain?
All chemical reactions need energy, and ATP (adenosine triphosphate) is the bodies energy storing and providing molecule. In the process of cellular respiration, two ATP are used, and four are formed, so there is a net gain of two ATP. For some organisms this is enough, but in many organisms, a higher yield of ATP is needed. The body uses what is known as the kreb cycle, which is much more complex, and produces around 36 molecules of ATP.
What is the four steps of cellular respiration?
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.
Which process can be described as a four-step process for producing ATP from glucose a. Cellular respiration b. Chemical reaction c. Photosynthesis d. Osmosis?
The process that can be described as a four-step process for producing ATP from glucose is a. Cellular respiration. This process involves glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation, which collectively convert glucose into ATP, carbon dioxide, and water.
