What is Krebs cycle diagram?
The Krebs cycle starts with pyruvic acid from glycolysis. Each small circle in the diagram represents one carbon atom. For example, citric acid is a six carbon molecule, and OAA (oxaloacetate) is a four carbon molecule. Follow what happens to the carbon atoms as the cycle proceeds.
What is the Krebs cycle in simple terms?
: a sequence of reactions in the living organism in which oxidation of acetic acid or acetyl equivalent provides energy for storage in phosphate bonds (as in ATP) — called also citric acid cycle, tricarboxylic acid cycle.
What are the inputs and outputs of Krebs cycle?
As you should know from studying the Krebs cycle, metabolic cycles involve inputs and outputs, and some molecules are recycled to complete the cycle. In the case of the Calvin Cycle , the input molecules are carbon dioxide, ATP, and NADPH. The output molecules are sugar, ADP, NADP+, and inorganic phosphate (Pi).
What is the starting material in the Krebs cycle?
The primary substrates, or raw materials, for the Krebs cycle are glucose (extracted from carbohydrate foods) and fatty acids. Most of the glucose forms oxaloacetate in the Krebs cycle, while the remaining glucose combines with the fatty acids and amino acids to form acetyl coenzyme acetate ( acetyl CoA ).
What does the Krebs cycle make?
The Krebs cycle creates important chemicals like NADH that assist in the electron transport chain that is used to create ATP. It also produces a number of secondary products that are used in other biochemical reactions. All aerobic (oxygen-breathing) organisms use the citric acid cycle to generate their energy.
What is an example of Krebs cycle?
The citric acid cycle (The Krebs Cycle) is a good example of an amphibolic pathway because it functions in both the degradative (carbohydrate, protein, and fatty acid) and biosynthetic processes. The cycle occurs on the cytosol of bacteria and within the mitochondria of Eukaryotic cells.
