Question

order the atoms involved in cellular respiration from most prevalent to least. (1 point)
o h, c, o
o o, h, c
o c, h, o
o h, o, c

Explanation:

Cellular respiration involves the breakdown of glucose ($C_6H_{12}O_6$) and use of oxygen ($O_2$). In glucose, there are 6 carbon (C), 12 hydrogen (H) and 6 oxygen (O) atoms. Oxygen is also consumed in the process. Hydrogen atoms are involved in electron - transport chain and proton - gradient formation. Oxygen is the final electron acceptor. Carbon is released as carbon dioxide ($CO_2$). The most prevalent atom is hydrogen (H), followed by oxygen (O) and then carbon (C).

Answer:

A. H, C, O
