Final answer:
Photosynthesis in plant cells converts sunlight into chemical energy in the form of glucose, which is then used by athletes for energy.
Step-by-step explanation:
The energy for an athlete originates from the sun through the process of photosynthesis. Photosynthesis occurs in the chloroplasts of plant cells, where sunlight is converted into chemical energy in the form of glucose. This energy is then released during cellular respiration, which generates ATP (adenosine triphosphate), the main source of energy for muscle contraction and other cellular processes in the athlete's body.
An athlete's energy originates from the sun through photosynthesis, where chloroplasts in plant cells convert sunlight into chemical energy in ATP and glucose. The athlete then uses the energy stored in glucose through cellular respiration to fuel their physical activities.
The energy that fuels an athlete's activities originates from the sun through the process of photosynthesis. This process begins with sunlight being captured by chlorophyll within the chloroplasts of plant cells. The light reactions convert solar energy into chemical energy stored in ATP and NADPH. These molecules are then used in the Calvin Cycle to create glucose, which plants use to store energy. When an athlete consumes plant-derived foods, they harness the energy stored in the chemical bonds of glucose. Through the process of cellular respiration, the athlete's cells break down glucose to form ATP, which is then used to fuel muscle contractions during physical activity.
To specifically answer the student's question, option b) 'Energy transfer occurs in the chloroplasts, where sunlight is converted into ATP' is partially correct but should specify that ATP is produced during the light reactions of photosynthesis and used alongside NADPH in the Calvin Cycle to create glucose.
