Step 1
Which labelled structure contains enzymes for cellular respiration?
Answer
The labelled structure that contains enzymes for cellular respiration is C. The mitochondria, which are indicated by label C in the diagram, are the organelles responsible for cellular respiration. They convert nutrients into energy through a series of metabolic processes, primarily involving the Krebs cycle and oxidative phosphorylation. Enzymes for these processes are located in the inner mitochondrial membrane and the mitochondrial matrix.
