Which of the following reactions in glycolysis produce ATP or NADH?
a. 1,3-bisphosphoglycerate to 3-phosphoglycerate

검증된 단계별 안내

Step 1: Understand the context of glycolysis, which is a metabolic pathway that breaks down glucose into pyruvate, producing ATP and NADH as energy carriers.

Step 2: Recall that ATP is produced during substrate-level phosphorylation, and NADH is produced during oxidation-reduction reactions in glycolysis.

Step 3: Analyze the given reaction: 1,3-bisphosphoglycerate to 3-phosphoglycerate. This step involves the transfer of a phosphate group from 1,3-bisphosphoglycerate to ADP, forming ATP. This is an example of substrate-level phosphorylation.

Step 4: Note that this reaction does not involve the transfer of electrons or hydrogen atoms, so NADH is not produced in this step.

Step 5: Conclude that the reaction from 1,3-bisphosphoglycerate to 3-phosphoglycerate produces ATP but not NADH.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Glycolysis

Glycolysis is a metabolic pathway that converts glucose into pyruvate, producing energy in the form of ATP and NADH. It occurs in the cytoplasm of cells and consists of ten enzyme-catalyzed reactions. Understanding glycolysis is essential for identifying which specific reactions yield ATP or NADH.

ATP Production

ATP (adenosine triphosphate) is the primary energy currency of the cell. In glycolysis, ATP is produced through substrate-level phosphorylation, where a phosphate group is directly transferred to ADP from a phosphorylated intermediate. Recognizing the steps in glycolysis that generate ATP is crucial for answering questions about energy yield.

NADH Production

NADH (nicotinamide adenine dinucleotide) is a coenzyme that plays a key role in cellular respiration by carrying electrons to the electron transport chain. In glycolysis, NADH is produced during the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate. Identifying the reactions that produce NADH is important for understanding the overall energy balance of glycolysis.
