Why is cellular respiration not 100 efficient?

Is cellular respiration 100\% efficient? No, aerobic cell respiration converts ~36\% of the energy in glucose into ATP. The other ~64\% is lost as heat.

What is the maximum efficiency for aerobic respiration?

Overall, aerobic respiration converts about 40\% of the available energy of glucose into ATP. The remaining 60\% is lost as heat and helps to generate your relatively high body temperature. 40\% efficiency may seem poor but it is several times more efficient than the best automobile engines.

What is the maximum number of ATP molecules produced during aerobic respiration?

38
The maximum number of ATP molecules that can be produced during aerobic respiration is 38.

Why is that aerobic respiration more efficient?

Aerobic respiration is more efficient than anaerobic respiration because aerobic respiration yields 6 times more energy as compared to anaerobic respiration. > Aerobic respiration is more efficient than anaerobic respiration because aerobic respiration yields more energy as compared to anaerobic respiration.

What are the disadvantages of aerobic respiration?

Disadvantages: Aerobic respiration is relatively slow and requires oxygen….Muscle Metabolism

• Within the muscle fiber. ATP available within the muscle fiber can maintain muscle contraction for several seconds.
• Creatine phosphate.
• Glucose stored within the cell.
• Glucose and fatty acids obtained from the bloodstream.

Is aerobic respiration more or less efficient than glycolysis?

Aerobic respiration is much more efficient than anaerobic glycolysis, yielding 36 ATP per molecule of glucose, as opposed to two ATP produced by glycolysis.

Why does aerobic respiration yield fewer molecules of ATP than the theoretical maximum?

In the last stage of respiration, some protons leak through the inner mitochondrial membrane back inside the matrix, so proton motive force which spins the headpiece of ATP synthase to produce ATP is decreased, hence less ATP produced.

Why is the actual ATP yield of aerobic respiration often less than the maximum possible yield of 38 ATP?

Why is the actual ATP yield of aerobic respiration often less than the maximum possible yield of 38 ATP? Glycolysis cannot occur in an anaerobic environment. Nitrogen is fixed to ammonia by cyanobacteria and other microbes.

Why is an aerobic respiration less efficient?

Much less energy is released during anaerobic respiration than during aerobic respiration. This is because the breakdown of glucose is incomplete. Anaerobic respiration produces an oxygen debt. This is the amount of oxygen needed to oxidise lactic acid to carbon dioxide and water.

Why is anaerobic respiration so less efficient than aerobic respiration?

Aerobic and anaerobic respiration each have advantages under specific conditions. Aerobic respiration produces far more ATP, but risks exposure to oxygen toxicity. Anaerobic respiration is less energy-efficient, but allows survival in habitats which lack oxygen.

Is aerobic respiration more or less efficient than glycolysis explain your answer?

What is the chemical equation for aerobic respiration?

Aerobic respiration is a biological process in which food glucose is converted into energy in the presence of oxygen. The chemical equation of aerobic respiration is as given below-. Glucose (C6H12O6) + Oxygen 6 (O2) → Carbon-dioxide 6 (CO2) + Water 6 (H2O) + Energy (ATP) According to the above-given chemical equation,

How much energy is released during the process of aerobic respiration?

The 2900 kJ of energy is released during the process of breaking the glucose molecule and in turn, this energy is used to produce ATP – Adenosine Triphosphate molecules which are used by the system for various purposes. Aerobic respiration process takes place in all multicellular organisms including animals, plants and other living organisms.

Why is aerobic respiration more efficient than anaerobic?

Aerobic respiration is much more efficient at making ATP than anaerobic processes like fermentation. Without oxygen, the Krebs Cycle and the Electron Transport Chain in cellular respiration get backed up and will not work any longer.

How many ATP are produced from one glucose molecule in aerobic respiration?

In this phase, the large amounts of ATP molecules are produced by transferring the electrons from NADH and FADH. A single molecule of glucose creates a total of 34 ATP molecules. Aerobic respiration is the process of utilisation of oxygen to breakdown glucose, amino acids, fatty acids to produce ATP.
