Question

1. which of the following is the correct equation for cellular respiration?

$6 o_2 + 6 h_2o -> 6 co_2 + c_6h_{12}o_6 + 36 atp$
$6 o_2 + c_6h_{12}o_6 -> 6 co_2 + 6 h_2o + 36 atp$
$c_6h_{12}o_6 + 36 atp -> 6 co_2 + 6 h_2o + 6 o_2$
$6 co_2 + 6 h_2o -> 6 o_2 + c_6h_{12}o_6 + 36 atp$
when oxygen is not present, cells carry out a process called:
the krebs cycle
photosynthesis
fermentation
aerobic cellular respiration

Explanation:

For the first question, cellular respiration is the process where glucose (\(C_{6}H_{12}O_{6}\)) reacts with oxygen (\(O_{2}\)) to produce carbon dioxide (\(CO_{2}\)), water (\(H_{2}O\)), and ATP. The correct reactants are \(O_{2}\) and \(C_{6}H_{12}O_{6}\), and the correct products are \(CO_{2}\), \(H_{2}O\), and ATP.
For the second question, when oxygen is not present, cells carry out fermentation. The Krebs Cycle and aerobic cellular respiration require oxygen. Photosynthesis is a process in plants to produce glucose using \(CO_{2}\) and \(H_{2}O\) with light energy.

Answer:

1. \(6O_{2}+C_{6}H_{12}O_{6}\to6CO_{2}+6H_{2}O + 36ATP\)
2. Fermentation
