glucose. Cells are broken down into simple food molecules. Cellular Respiration undergoes two processes: Glycolysis and The Krebs Cycle. In Glycolysis enzymes help in chemical reactions that break down oxygen and glucose into different molecules. Pyruvic and 2 molecules of ATP are produced during Glycolysis. In the Krebs cycle nine reactions occur. Pyruvic acid is broken down and carbon dioxide and energy are given off. This energy is then used to create ATP and water. 5. Why are photosynthesis

catalyzes the reaction of pyruvate and lactate of NADH AND NAD+. As it converts pyruvate‚ the final product of glycolysis‚ to lactate‚ if oxygen is absent or in minimal amounts‚ it will perform the opposite reaction during another cycle‚ which is the Cori cycle. The Cori cycle takes place in the liver. When we exercise our cells get significant amounts of oxygen and sugar is broken down quickly and very efficiently. On the other hand‚ when we start to run or really push our bodies to the limit‚ there

driven by a diffusion force similar to osmosis‚ this process is referred to as ___________. 9. The return of the protons into the mitochondrial matrix through mitochondrial membrane channels occurs by the process of _________. 10. The amino acids must be first __________ before they can be used in catabolic reactions. 11. Fats undergo a process called ____ oxidation‚ in which the products are acetyl coenzyme molecules. 12. The first stage of cellular respiration‚______________‚ occurs

involve the conversion of NAD+ to NADH. Because both glycolysis and the Krebs cycle produce NADH‚ both of these processes shut down when there is no available NAD+. 5. If the Krebs cycle does not require oxygen‚ why does cellular respiration stop after glycolysis when no oxygen is present? When no oxygen is present‚ oxidative phosphorylation cannot occur. As a result‚ the NADH produced in glycolysis and the Krebs cycle cannot be oxidized to NAD+. When no NAD+ is available‚ pyruvate cannot be converted

Cellular respiration includes the processes of glycolysis‚ krebs cycle‚ and the electron transport chain. Glycolysis is used to convert glucose to produce two pyruvate as well as 4 ATP’s and 2 NADH but uses 2 ATP to have a net product of 2 ATP and 2 NADH. The krebs cycle converts pyruvate to Acetyl CoA‚ which produces 2 ATP‚8 NADH‚ and 2 FADH’s per glucose molecule. Electron transport Chain is the last and most important

glycolysis‚ glucose (6 C) is broken into 2 pyruvic acid (3 C) 2 ATP is produced and 2 NADH come in to keep the energy released from broken bonds. The Bridge Before going to the Kreb’s cycle 2 pyruvic acid (3C) becomes 2 Acetyl CoA (2 C). As a result‚ 2CO2 is produced and 2NADH comes in the keep the energy released. Kreb’s Cycle Takes place in the cytoplasm for prokaryotes or in the mitochondria for eukaryores. Two Acetyl CoA spin around the Kreb’s cycle—one time for each. At the end‚ 2 Acetyl CoA

1 Two critical ingredients required for cellular respiration are glucose and oxygen. Cellular Respiration‚ process in which cells produce the energy they need to survive. In cellular respiration‚ cells use oxygen to break down the sugar glucose and store its energy in molecules of adenosine triphosphate (ATP). Cellular respiration is critical for the survival of most organisms because the energy in glucose cannot be used by cells until it is stored in ATP. Cells use ATP to power virtually all of

organisms produce adenosine triphosphate (ATP) as a source of energy for cellular work‚ using cellular respiration. Cellular respiration is a process that involves glycolysis -breaking down glucose into two molecules of 3- carbon pyruvate‚ the Krebs cycle - oxidizing organic fuel derived from pyruvate-‚ and the electron transport chain - moving electrons through a series of protein complexes to generate ATP (Reece‚ et.al‚ 2011). The process of cellular respiration occurs in the Cytoplasm and the Mitochondria
