The Krebs cycle (also known as the citric acid cycle) requires oxygen, acetyl-CoA (produced from the breakdown of carbohydrates, fats, and proteins), and enzymes to proceed. This cycle takes place in the mitochondria of cells and is essential for the production of energy in the form of ATP.
What else can I help you with?
What is starting molecule for Krebs cycle?
The Krebs cycle starts with acetyl CoA, and combines with oxaloacetate to form citrate, a six-carbon molecule. Citrate is further oxidized until oxaloacetate is again reached at the end to restart..
What does the carbon atoms in pyruvic acid end up as in the atmosphere following the Krebs cycle?
if you're talking about after the carbons are exhaled through CO2 the the pyruvate need to give off more CO2 for it to be Acetyl Co-A to pass through the mitochondrial membrane to go through the Krebs cycle. so in the Krebs cycle it's acetyl Co-A. Then it goes to the electron transport chain.
What happens in every sequence of the dark Reaction?
here are three things this cycle go through. The first thing that must happen is that the reaction must fixate the carbon dioxide. Then the reduction of 3PG that was produced in the first reaction. Then this will form carbohydrates. Through this reaction it uses phosphorylation. The reaction will then need to regenerate the carbon dioxide. After this whole cycle, the final product will then be trios phosphate.
Enzymes work by bringing reactants together at a higher energy level than they would need in an uncatalysed reaction?
Enzymes lower the activation energy required for a reaction to occur by providing an alternative pathway for the reaction. This allows the reaction to proceed more quickly and efficiently than in an uncatalyzed reaction. The enzyme itself remains unchanged at the end of the reaction and can be used again.
How are photosynthesis transpiration and respiration related?
both are processes that provide energy for cells/organisms. photosynthesis provides energy for photoautotrophs through light reactions in the thylakoids and the Calvin cycle. ellular respiration gives hetertrophs the energy they need through glycolysis, the Krebs cycle, and electron transport system
What does Krebs cycle need to proceed?
Pyruvates
Is the Krebs cycle part of the photosynthesis?
No, the Krebs cycle is not part of photosynthesis. The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions that occur in the mitochondria of cells to produce energy from the breakdown of carbohydrates, fats, and proteins. Photosynthesis is the process by which plants and other organisms convert light energy into chemical energy in the form of glucose.
What is starting molecule for Krebs cycle?
The Krebs cycle starts with acetyl CoA, and combines with oxaloacetate to form citrate, a six-carbon molecule. Citrate is further oxidized until oxaloacetate is again reached at the end to restart..
What type of chemical reaction is need to absorb energy to proceed?
Endothermic Reaction.... (Just to help you out someone helped me with this question and I GOT IT CORRECT!)

If a cell has no oxygen what stages of aerobic cellular respiration can still run?
If there is no oxygen available, only glycolysis can still run in anaerobic conditions. The Krebs cycle and electron transport chain, both of which require oxygen, cannot proceed. Glycolysis produces ATP by breaking down glucose into pyruvate without the need for oxygen.
What gas is needed in dark reaction?
CO2 is needed for it. That is to get carbon
Why are the reactions considered to be part of a cycle?
Reactions are considered part of a cycle when they occur in a recurring sequence, with the products of one reaction serving as the reactants for the next. This cyclic nature allows the reactions to continue in a continuous loop without the need for external sources of reactants. Examples include the Krebs cycle in cellular respiration and the Calvin cycle in photosynthesis.
A synthesis reaction will occur spontaneously if heat of formation of product is?
negative. This indicates that the reactants have higher energy than the products, allowing the reaction to proceed without the need for external energy input.
If heat must be added to a chemical reaction for the reaction to take place the reaction is?
Endothermic reactions need heat. Exothermic reactions give off heat.
What happens to acetyl CoA if its not needed in the Krebs cycle?
Acetyl CoA is multifunctional; it can be used to produce fat or ATP. If the body needs energy, acetyl CoA enters the Krebs cycle. If the body doesn't need energy, acetyl CoA is channelled into an anabolic pathway that synthesizes lipids as a way of storing large amounts of energy as fat.
