What process occurs in Box A?
a. A scheme of cellular respiration. In Box A, which is located in the cytosol, glucose turns into pyruvate with the release of ATP and electrons carried by NADH.
b. Pyruvate from this stage is used in a cycle in Box B, which is located in the mitochondrion.
c. As a result, ATP, CO^2, and electrons carried by NADH and FADH^2 are released.
d. The electrons carried by NADH and FADH^2 from Boxes A and B are used in Box C (inside the mitochondrion) for the transformation of a substance marked D (that comes from the cytosol) into a substance marked E (released to the cytosol) with the release of ATP.

Step 1I'll solve this problem step by step, focusing on the cellular respiration process described in the question.
Step 2: Identify the Process in Box A
The process in Box A is glycolysis, which occurs in the cytosol of the cell. Key characteristics of glycolysis: - Occurs in the cytoplasm (cytosol) - Breaks down glucose into pyruvate - Produces a net gain of ATP - Generates NADH electrons
Final Answer
In Box A, glycolysis occurs, converting glucose to pyruvate, producing ATP and NADH electrons in the cytosol.
