The correct answer is C, Oxygen.
During aerobic cellular respiration, oxygen combines with hydrogen ions and water is released as a by-product of respiration.
Explanation;
Cellular respiration allows organisms to release energy stored in chemical bonds of glucose, and other nutrients. The energy in glucose or other nutrients such as fats is used to produce ATP, which cells use to supply their energy needs. During aerobic respiration (in presence of oxygen), oxygen is reduced and water is produced together with carbon dioxide as by-products.
Water only needed for Photosynthesis.. Not both of Photosynthesis and Respiration..
There are two oxygen atoms. The OH is in parentheses with the 2 after it to indicate that there are two OH molecules, each containing on atom of oxygen.
I think it’s either the first or last one
No because of water evaporates and the cumebous and unbous layers take in the vapperation of the water that humans use and other plants and animals. so no
