Briefly explain the overall processes of photosynthesis and cellular respiration. Include a brief explanation of autotrophs and heterotrophs in your answer

Question

What will be an ideal response?

Answer 1

Photosynthesis is performed by autotrophs. In photosynthesis, light energy is converted into chemical energy (stored within the bonds of glucose). Water and carbon dioxide are consumed, and oxygen is released. In most autotrophs, photosynthesis occurs in the chloroplasts. Cellular respiration represents the reverse chemical process. It is performed by both autotrophs and heterotrophs to meet their energy needs. In cellular respiration, oxygen is consumed, and the bonds of glucose are broken to release energy, which is then used for work within the cell. Along with the energy, carbon dioxide and water are end products, and heat is produced. In most organisms, cellular respiration takes place in the mitochondria.
