1. chlorophyll is found in theof plant cells

and its primary role is toduring
photosynthesis.

Explanation:

1. Cellular respiration is the process by which cells break down glucose in the presence of oxygen to produce carbon dioxide, water, and energy (ATP). The balanced chemical equation is \(C_6H_{12}O_6+6O_2

ightarrow6CO_2 + 6H_2O+ATP\).

1. Photosynthesis is the process by which plants use carbon dioxide, water, and light energy to produce glucose and oxygen. The balanced chemical equation is \(6CO_2+6H_2O + light

ightarrow C_6H_{12}O_6+6O_2\).

1. In cellular respiration, glucose (\(C_6H_{12}O_6\)) is oxidized (loses electrons/hydrogen) and oxygen (\(O_2\)) is reduced (gains electrons/hydrogen).
2. The three main stages of cellular respiration are glycolysis (breaks down glucose to pyruvate), the Krebs cycle (oxidizes acetyl - CoA), and the electron transport chain (generates ATP through oxidative phosphorylation).
3. During glycolysis, one molecule of glucose (\(C_6H_{12}O_6\)) is broken down into two molecules of pyruvate (\(C_3H_4O_3\)).
4. The main energy - carrying molecule produced during cellular respiration is ATP (adenosine triphosphate). Approximately 36 - 38 ATP molecules are produced from one glucose molecule.
5. Chlorophyll is found in the thylakoid membranes (or chloroplasts) of plant cells. Its primary role is to absorb light energy during photosynthesis.

Answer:

1. \(C_6H_{12}O_6\); \(ATP\)
2. \(light\); \(C_6H_{12}O_6\)
3. \(C_6H_{12}O_6\); \(O_2\)
4. glycolysis; Krebs; electron
5. pyruvate (\(C_3H_4O_3\))
6. \(ATP\); \(36 - 38\)
7. thylakoid membranes (or chloroplasts); absorb light energy
