Where in the cell does the Krebs (citric acid) cycle occur Quizlet?
The Krebs cycle is a process that involves the breakdown of food to produce energy. In humans, the Krebs cycle is located in the mitochondria, which is located in every cell of the body. The Krebs cycle takes place in a chemical reaction called oxidative phosphorylation. This chemical reaction generates energy for the cell by combining the food we eat with oxygen.
What part of the Krebs (citric acid) cycle does glucose go?
In order to use glucose as a source of energy, it must first be broken down into smaller chemical compounds. The first step in the process is glycolysis—a process in which glucose is broken down into two smaller molecules: glucose-6-phosphate (G-6-P) and free-energy-rich pyruvate. These two chemicals go on to the next step of the Krebs (citric acid) cycle which is the TCA cycle (also known
What does the Krebs (citric acid) cycle occur in?
The Krebs cycle is a series of chemical reactions that takes place inside the cells of plants, fungi, and some bacteria. It is the final part of a process called oxidative phosphorylation, which produces energy in aerobic respiration (as opposed to anaerobic respiration, which does not use oxygen). The Krebs cycle is named after German biochemist Hans Krevos, who first proposed the model in 1925.
What processes in the cell do enzymes in the Krebs (citric acid) cycle catalyze?
The Krebs (citric acid) cycle is responsible for generating the energy needed for a cell to function. It involves a series of chemical reactions that take place in the mitochondria. These reactions occur in a manner that converts the energy stored in food into energy that can be used by the cell. This process generates a byproduct known as Adenosine Triphosphate (ATP).

The citric acid cycle is the most important step of aerobic respiration because it generates the two main by-products of cellular respiration: Adenosine triphosphate (ATP) and nicotinamide adenosine dinucleotide (NADH). This reaction takes place in the matrix of the four mitochondrial cristae, the mitochondrial ‘chambers’.
