Solution
Solution Steps
Step 1: Identify the process depicted in the diagram
The diagram shows a mitochondrion, which is the site of cellular respiration. The inputs are oxygen (O₂) and sugar, and the outputs are water (H₂O), carbon dioxide (CO₂), and a substance labeled "X".
Step 2: Determine the product labeled "X"
In cellular respiration, the mitochondrion converts sugar and oxygen into water, carbon dioxide, and ATP (adenosine triphosphate). ATP is the primary energy carrier in cells.
Step 3: Match "X" with the correct term
Given the options:
ATP
Chlorophyll
Antibodies
Glucose
The most appropriate term for "X" is ATP, as it is the energy currency produced during cellular respiration.
Final Answer
The term most appropriately represented by "X" is (1) ATP.
