Responses
the process of capturing the sun’s energy, converting it into sugar, and storing it in tissues
the process of capturing the sun’s energy, converting it into sugar, and storing it in tissues
the process of capturing the sun’s energy, converting it into oxygen, and releasing it into the atmosphere
the process of capturing the sun’s energy, converting it into oxygen, and releasing it into the atmosphere
the process of using the chemical energy from food and oxygen molecules to power life processes
the process of using the chemical energy from food and oxygen molecules to power life processes
the process of using the chemical energy from hydrogen and oxygen molecules to power life processes
The correct answer is:
the process of using the chemical energy from food and oxygen molecules to power life processes
To arrive at this answer, we need to understand the definition of cellular respiration. Cellular respiration is a process that occurs in cells, where they break down molecules of food (usually glucose) in the presence of oxygen to release energy. This energy is then used for various life processes, such as growth, movement, and reproduction.
Option 1 can be eliminated because it mentions "converting the sun's energy into sugar," which is actually the process of photosynthesis, not cellular respiration. Similarly, option 2 can be eliminated for the same reason - it refers to the conversion of sun's energy into oxygen, which is again related to photosynthesis, not cellular respiration.
Option 4 can be eliminated because it mentions the use of hydrogen and oxygen molecules to power life processes, which is not true in the case of cellular respiration. Instead, cellular respiration specifically uses food molecules and oxygen.
Hence, the correct answer is option 3 - the process of using the chemical energy from food and oxygen molecules to power life processes.
