Label the mitochondrion to indicate the location of glycolysis, the citric acid cycle, and electron transport chains.

검증된 단계별 안내

Step 1: Understand the locations of the three processes in cellular respiration. Glycolysis occurs in the cytoplasm, the citric acid cycle (Krebs cycle) occurs in the mitochondrial matrix, and the electron transport chain is located in the inner mitochondrial membrane.

Step 2: Identify the parts of the mitochondrion in the image. Label 'a' points to the outer membrane, 'b' points to the inner membrane with folds called cristae, and 'c' points to the matrix inside the inner membrane.

Step 3: Since glycolysis occurs in the cytoplasm, it is located outside the mitochondrion, so it should be labeled outside the structure shown in the image.

Step 4: The citric acid cycle takes place in the mitochondrial matrix, so label 'c' as the location of the citric acid cycle.

Step 5: The electron transport chain is embedded in the inner mitochondrial membrane, so label 'b' as the location of the electron transport chain.

주요 개념

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

Glycolysis Location

Glycolysis is the metabolic pathway that breaks down glucose into pyruvate, producing ATP and NADH. This process occurs in the cytoplasm of the cell, outside the mitochondrion, and is the first step in cellular respiration.

Citric Acid Cycle Location

The citric acid cycle (Krebs cycle) takes place in the mitochondrial matrix, the innermost compartment of the mitochondrion. It processes pyruvate into carbon dioxide while generating NADH and FADH2 for the electron transport chain.

Electron Transport Chain Location

The electron transport chain is located in the inner mitochondrial membrane. It uses electrons from NADH and FADH2 to create a proton gradient that drives ATP synthesis through oxidative phosphorylation.
