The oxygen produced by photosynthesis comes from water. During the process, water molecules are split, releasing oxygen as a byproduct.
What makes photosynthesis and cellular respiration similar?(1 point)
Responses
Both produce an output of glucose, water, and carbon dioxide.
Both produce an output of glucose, water, and carbon dioxide.
Both involve ATP molecules.
Both involve ATP molecules.
Both involve combinations of carbon, hydrogen, and oxygen.
Both involve combinations of carbon, hydrogen, and oxygen.
Both require the input of light energy.
Responses
Both produce an output of glucose, water, and carbon dioxide.
Both produce an output of glucose, water, and carbon dioxide.
Both involve ATP molecules.
Both involve ATP molecules.
Both involve combinations of carbon, hydrogen, and oxygen.
Both involve combinations of carbon, hydrogen, and oxygen.
Both require the input of light energy.
The correct response is: Both involve combinations of carbon, hydrogen, and oxygen.
While photosynthesis produces glucose and oxygen from carbon dioxide and water using light energy, cellular respiration uses glucose and oxygen to produce carbon dioxide, water, and ATP. Both processes involve the same fundamental elements (carbon, hydrogen, and oxygen) but have different outputs and energy transformations.

The process that transfers carbon from the atmosphere to the biosphere is photosynthesis. During photosynthesis, plants absorb carbon dioxide from the atmosphere and convert it into organic compounds, thus incorporating carbon into the biosphere.
