Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is a product of the Electron Transport Chain?
A
CO2
B
O2
C
C6H1206
D
H2O
Explanation: 

Detailed explanation-1: -ATP is used by the cell for functioning cellular activities. The end products of the ETC or electron transport chain are the formation of ATP, NAD+, FAD, water, and protons.

Detailed explanation-2: -The end products of electron transport are NAD+, FAD, water and protons. The protons end up outside the mitochondrial matrix because they are pumped across the cristal membrane using the free energy of electron transport.

Detailed explanation-3: -Answer and Explanation: The electron transport chain produces three molecules of water for each three carbon sugar that is broken down during aerobic respiration. This means that each six carbon sugar produces six molecules of water when broken down.

Detailed explanation-4: -Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.
