Answer
A. The molecule represented by letter X in Process 1 is Adenosine Triphosphate (ATP).B. Both Process 1 and Process 2 occur in the cells of a green plant leaf.
Explanation
## Step 1: This problem pertains to two biological processes: cellular respiration and photosynthesis. The first process, cellular respiration, is a set of metabolic reactions that occur in cells of organisms to convert nutrients into adenosine triphosphate (ATP), and then to release waste products. The reactants are glucose and oxygen, and the products are water, carbon dioxide, and an energy-containing molecule: ATP.## Step 2: The equation mentioned in the question is a simplified form of the cellular respiration equation (Process 1):
. In this equation, X represents ATP, which is generated through the process. ATP is essentially the energy molecule for the cell, utilized for various functions.## Step 3: The interpretation is that "X" is ATP because that is the main purpose and output of cellular respiration. Just to clarify, Process 2 is Photosynthesis.## Step 4: The second part of the question asks which process occurs in the cells of a green plant leaf. The answer is both processes. Process 1, cellular respiration, occurs in all cells, including those of a green plant leaf. Process 2, photosynthesis, is the process by which green plants convert light energy, usually from the sun, into chemical energy in the form of glucose. Photosynthesis only occurs in the cells of green plants, algae, and some bacteria.
