Question
Why are NADH and FADH2 necessities in the electron transport chain?(1 point)
Responses
They move electrons to the electron transport chain.
They move electrons to the electron transport chain.
They move down the electron transport chain.
They move down the electron transport chain.
They remove electrons from the electron transport chain.
They remove electrons from the electron transport chain.
They accept electrons in order to power the electron transport chain.
The correct answer is: They move electrons to the electron transport chain.
NADH and FADH2 play a crucial role in the electron transport chain by transferring electrons to the chain. These molecules hold high-energy electrons and donate them to the electron transport chain, which is the final step in cellular respiration.
The correct formula for cellular respiration is: Glucose + oxygen → carbon dioxide + water + ATP
To determine the correct formula, we need to understand the process of cellular respiration. Cellular respiration is a biochemical process that occurs in cells to release energy from glucose and convert it into a usable form called ATP (adenosine triphosphate).
During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide, water, and ATP. Glucose provides the fuel for the reaction, while oxygen acts as the final electron acceptor in the electron transport chain. The waste products of this process are carbon dioxide and water, which are expelled from the cells.
Therefore, the correct formula would be: Glucose + oxygen → carbon dioxide + water + ATP. This formula correctly represents the inputs (glucose and oxygen) and the outputs (carbon dioxide, water, and ATP) of cellular respiration.
