What else can I help you with?
What are the two pathways found in both plants and animals?
Glycolysis and the Krebs cycle, also known as the citric acid cycle.
What molecules both enters AND exits the Kreb's cycle?
Pyruvic acid enters and carbon dioxide exits.
Is the Cori cycle the same as the Krebs cycle?
No, the Cori cycle and the Krebs cycle are not the same. The Cori cycle refers to the process in which lactate produced by anaerobic glycolysis in muscles is transported to the liver, where it is converted back into glucose. In contrast, the Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions in the mitochondria that generate energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. Both cycles are important for energy metabolism but serve different purposes.
What electron carrier function in the Krebs cycle?
NAD+ and FAD are electron carriers that function in the Krebs cycle to accept and transport electrons from various reactions within the cycle. They play a crucial role in transferring these electrons to the electron transport chain for ATP production.
How does the purpose of the Krebs cycle differ from the purpose of the Calvin cylce?
The Krebs Cycle's purpose is to produce ATP that cells can use, occurs in animal cells. The Calvin Cycle is in chloroplasts and is used to produce glucose for cells. *
What are the key differences between the Cori cycle and the Krebs cycle in cellular metabolism?
The Cori cycle and the Krebs cycle are both important processes in cellular metabolism, but they have different functions. The Cori cycle is involved in the conversion of lactate to glucose in the liver, while the Krebs cycle is a series of chemical reactions that produce energy in the form of ATP. In summary, the Cori cycle deals with lactate and glucose conversion, while the Krebs cycle generates energy for the cell.
What are the two pathways found in both plants and animals?
Glycolysis and the Krebs cycle, also known as the citric acid cycle.
What are the similarities between the Krebs Cycle and the Calvin cycle?
Similarity: They are both cycles, therefore both have a reactant that s regenerated. In the Krebs Cycle, oxaloacetate is regenerated. In the Calvin cycle, RuBP is regenerated (ribulose 1, 5-bisphosphate). Difference: Glucose is completely broken down in the Krebs Cycle to carbon dioxide, which in the Calvin Cycle, glucose is made as a product.
What molecules both enters AND exits the Kreb's cycle?
Pyruvic acid enters and carbon dioxide exits.
Where in the cell Krebs cycle and electron transport chain occur and whether they are anaerobic or aerobic?
The Krebs cycle (also known as the citric acid cycle) occurs in the mitochondrial matrix and is a key part of cellular respiration, which is aerobic. The electron transport chain takes place in the inner mitochondrial membrane and is also part of aerobic respiration. Both processes require oxygen to generate ATP efficiently.
Is the Cori cycle the same as the Krebs cycle?
No, the Cori cycle and the Krebs cycle are not the same. The Cori cycle refers to the process in which lactate produced by anaerobic glycolysis in muscles is transported to the liver, where it is converted back into glucose. In contrast, the Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions in the mitochondria that generate energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. Both cycles are important for energy metabolism but serve different purposes.
What electron carrier function in the Krebs cycle?
NAD+ and FAD are electron carriers that function in the Krebs cycle to accept and transport electrons from various reactions within the cycle. They play a crucial role in transferring these electrons to the electron transport chain for ATP production.
What is the substance that enters the Krebs cycle from glycolysis?
In Glycolysis, the final compound formed is Pyruvate. Now, pyruvate has to be transformed to Acetyl-CoA by the substitution of the carboxylic group with a Coenzyme A by pyruvate dehydrogenase. In real terms, Acetyl-CoA is the molecule that "switch on" the Krebs cycle.
What is the Oxidized form of the most common electron carrier needed in both glycolysis and Krebs cycle?
The oxidized form of the most common electron carrier needed in both glycolysis and the Krebs cycle is NAD+ (nicotinamide adenine dinucleotide). NAD+ accepts electrons during the oxidation of substrates and is converted to its reduced form, NADH, which then delivers the electrons to the electron transport chain for ATP production.
Which is capable of being reduced during either glycolysis or the Krebs cycle?
NAD+ (nicotinamide adenine dinucleotide) is capable of being reduced during either glycolysis or the Krebs cycle. It accepts electrons and a hydrogen ion to form NADH, which carries these high-energy electrons to the electron transport chain for ATP production.
What are the three processes of aerobic respiration?
The three processes of aerobic respiration are glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation. Glycolysis occurs in the cytoplasm, the citric acid cycle takes place in the mitochondria, and oxidative phosphorylation happens in the inner mitochondrial membrane.
What are the key differences between the Krebs cycle and the citric acid cycle, and how do they contribute to cellular respiration?
The Krebs cycle and the citric acid cycle are actually the same thing. They are both names for the same series of chemical reactions that occur in the mitochondria of cells. This cycle is a key part of cellular respiration, where glucose is broken down to produce energy in the form of ATP. The cycle involves a series of reactions that ultimately result in the production of ATP, carbon dioxide, and water.
