KERB Cycle

What are the stages of the KERB cycle?

• The stages of the KERB cycle are: Kinetic, Energy, Reaction, and Balance

• The stages of the KERB cycle are: Krebs, Electron transport chain, and Oxidative phosphorylation.

• The stages of the KERB cycle are: Ketchup, Eggplant, Radish, and Banana

• The stages of the KERB cycle are: Ketosis, Excretion, Respiration, and Breakdown

Explain the importance of the KERB cycle in cellular respiration.

• The KERB cycle, also known as the citric acid cycle or the tricarboxylic acid cycle, is important in cellular respiration as it is the final common pathway for the oxidation of fuel molecules, producing ATP and providing electrons for the electron transport chain.

• The KERB cycle is not important in cellular respiration

• The KERB cycle is only involved in photosynthesis

• The KERB cycle only produces water in cellular respiration

What is the first stage of the KERB cycle and what molecules are involved in it?

• The first stage of the KERB cycle is the Electron Transport Chain, and the molecules involved are ATP and NADH

• The first stage of the KERB cycle is the Calvin cycle, and the molecules involved are glucose and fructose

• The first stage of the KERB cycle is the Krebs cycle, also known as the citric acid cycle. The molecules involved in this stage are acetyl-CoA, oxaloacetate, and citrate.

• The first stage of the KERB cycle is the Glycolysis, and the molecules involved are pyruvate and lactate

Describe the role of NADH and FADH2 in the KERB cycle.

• NADH and FADH2 are involved in the synthesis of proteins in the Krebs cycle

• NADH and FADH2 are responsible for breaking down glucose in the Krebs cycle

• NADH and FADH2 are used to store excess water in the Krebs cycle

• NADH and FADH2 are electron carriers that donate electrons to the electron transport chain, leading to the production of ATP in the Krebs cycle.

Why is the KERB cycle considered a central metabolic pathway in cells?

• The KERB cycle is considered a central metabolic pathway in cells because it is not essential for cell function

• The KERB cycle is considered a central metabolic pathway in cells because it is only found in certain types of cells

• The KERB cycle is considered a central metabolic pathway in cells because it is involved in the production of energy (ATP) and the generation of precursor molecules for biosynthesis.

• The KERB cycle is considered a central metabolic pathway in cells because it is involved in the breakdown of waste products

What is the significance of the KERB cycle in the metabolism of carbohydrates, fats, and proteins?

• The KERB cycle is only significant in the metabolism of proteins

• The KERB cycle is not involved in the metabolism of macronutrients

• The KERB cycle only produces energy in the form of carbohydrates

• The KERB cycle, also known as the citric acid cycle or tricarboxylic acid cycle, is significant in the metabolism of carbohydrates, fats, and proteins as it is the final common pathway for the oxidation of these macronutrients, producing energy in the form of ATP and providing intermediates for the synthesis of other important molecules.

Explain the concept of substrate-level phosphorylation in the context of the KERB cycle.

• Substrate-level phosphorylation involves the transfer of a phosphate group from ATP to a substrate molecule

• Substrate-level phosphorylation is not a part of the KERB cycle

• Substrate-level phosphorylation is the process in which a phosphate group is transferred from a substrate molecule directly to ADP, forming ATP. In the context of the KERB cycle, substrate-level phosphorylation occurs during the conversion of succinyl-CoA to succinate, and during the conversion of phosphoenolpyruvate to pyruvate.

• Substrate-level phosphorylation occurs during the conversion of glucose to pyruvate in the KERB cycle

How does the KERB cycle connect with other metabolic pathways in the cell?

• The KERB cycle does not connect with other metabolic pathways

• The KERB cycle connects with other metabolic pathways in the cell through the exchange of intermediate metabolites, such as acetyl-CoA, NADH, and ATP, which are utilized in various other metabolic processes.

• The KERB cycle connects with other metabolic pathways through the exchange of water and carbon dioxide

• The KERB cycle connects with other metabolic pathways through the exchange of proteins and lipids

Discuss the regulatory mechanisms that control the activity of enzymes in the KERB cycle.

• pH levels

• Allosteric regulation, feedback inhibition, and post-translational modifications are the main regulatory mechanisms that control enzyme activity in the KERB cycle.

• Temperature changes

• Genetic mutation
