What is the correct sequence of electron travels during aerobic respiration?

Another name for aerobic respiration is cellular respiration; this is when there is a conversion of nutrients to energy. The energy produced that is within the cell is called adenosine triphosphate or ATP. The correct sequence of electron travel during aerobic respiration is Food- NADH-electron transport chain – oxygen. The process is explained as follows.

Electrons are picked up from the food we eat by the NADH and FADH; through the electron pump, the electron is transferred to the electron transport chain due to the activity of pump electrochemical gradient is created.

ATP is generated from the electrochemical gradient with the help of an enzyme called the ATP synthase. The last process in aerobic respiration occurs when an electron is donated to oxygen to produce water.

Option B - Food -> NADH -> Electron transport chain -> oxygen is the correct sequence of electron travel during aerobic respiration.

In aerobic respiration (also known as cellular respiration) electrons travel in this sequence: electrons are picked up from the food by NADH and FADH, the electron picked is then transferred to the electron transport chain through a proton pump, the activity of the pump creates an electrochemical gradient, an enzyme called ATP synthase uses the electrochemical gradient produced to generate ATP. The last acceptor of an electron in aerobic respiration is oxygen, an electron is donated to oxygen to produce water.

Another name for aerobic respiration is cellular respiration. This is when there is a conversion of the nutrients to the energy. This energy within the cell is called adenosine triphosphate or ATP. After that, whatever is left over is waste. The waste is removed. Electrons do travel downhill during aerobic respiration. NADH is nicotinamide adenine dinucleotide. During this process, the food or nutrients are taken into the cell and then the electron transport chain moves the nutrients.

The electron donor takes in and transports the nutrients which is then accepted by the electron acceptor. Then is becomes oxygen. Some of the nutrients include sugar, amino acids and fatty acids. The electron acceptor is most likely going to be molecular oxygen.
