Biology

Analyze the diagram:

Glucose undergoes process ① to form X. Since glucose is broken down into pyruvate in glycolysis, X is pyruvate, and process ① is glycolysis.

Pyruvate (X) undergoes process ② to release CO₂. This is the process of pyruvate oxidation and the citric - acid cycle (in aerobic respiration).

After process ②, there is process ③ which may be related to the electron - transport chain and ATP production.

Analyze each option:

Option A:

Escherichia coli is a prokaryote. Glycolysis (process ①) occurs in the cytoplasmic matrix of both prokaryotic and eukaryotic cells. So, this statement is correct.

Option B:
