Is cellular respiration more efficient than photosynthesis?

Why is cellular respiration not efficient?

Explanation: Cellular respiration is only about 38% efficient, with the rest of the energy in glucose lost as heat. Water and carbon dioxide are not used to store energy. Fats can be synthesized from acetyl CoA and glycerol, but are not generally created in large quantities during cellular respiration.

How is cellular respiration more efficient than fermentation?

Cellular respiration produces 38 ATP, while fermentation produces only 2 ATP. 4. Cellular respiration is more efficient than fermentation in the generation of ATP. … The energy produced in fermentation can be used when energy production in cellular respiration slows down due to insufficient oxygen supply.

How efficient is this process of cellular respiration compared to a car consuming gasoline?

efficiency of this process in cells to the efficiency of a gasoline automobile engine. … With its ability to produce 32 ATP molecules per 1 glucose molecule, which is a conversion of about 34% of the energy that was initially in glucose, cellular respiration is actually a quite efficient reaction when compared to others.

What are the benefits of cellular respiration over anaerobic respiration?

Advantages of Aerobic Respiration

What is meant by the statement aerobic respiration is more efficient?

Answer : Aerobic respiration is more efficient because: … Efficiency is attributed to the number of ATP produced from one molecule of glucose. In Aerobic respiration produces 38 ATP molecules from a single glucose molecule while Anaerobic respiration produces only 2 ATP molecules from a single glucose molecule.

Why is fermentation less efficient at supplying energy compared to aerobic respiration?

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. This forces the cell to undergo the much less efficient fermentation.

Why is aerobic cellular respiration considered much more efficient than anaerobic glycolysis alone?

Explanation: Glycolysis breaks the glucose molecule into two pyruvate molecules, and they still have high energy bonds. These bond are broken during the aerobic respiration part and the energy released from them is stored in the ATP molecules which will then be used by the cell as an energy source.

How does cellular respiration differ from alcoholic fermentation?

Cellular respiration uses oxygen in the chemical reaction that releases energy from food. Fermentation occurs in an anaerobic or oxygen-depleted environment. Because fermentation doesn’t use oxygen, the sugar molecule doesn’t break down completely and so releases less energy.

Does cellular respiration produce more energy than fermentation?

Cellular respiration, like burning, results in the complete oxidation of glucose into CO2 and water. Fermentation, on the other hand, does not fully oxidize glucose. Instead, small, reduced organic molecules are produced as waste. As a result, cellular respiration releases more energy from glucose than fermentation.

What does cellular respiration have to do with metabolic processes?

Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products.

Why is anaerobic respiration less efficient than aerobic respiration?

Anaerobic respiration is a process in which energy is released from glucose without requiring oxygen. It is less efficient than aerobic respiration as it releases less energy than the energy released inaerobic respiration.

What happens if cellular respiration is not occurring properly?

Without the process of cellular respiration, there is no gaseous exchange and the cells, tissue and other organs die due to the lack of oxygen and by the accumulation of carbon dioxide within the cells and tissues.

Why is cellular respiration more important than photosynthesis?

Photosynthesis serves as the primary source of energy in plants while cellular respiration breaks down the glucose in the cell to provide energy to carry out life processes.

Why are cellular respiration and photosynthesis complementary processes?

Photosynthesis and cellular respiration are complementary because both depend on the inputs and outputs of both processes to continue. Photosynthesis requires CO2, which cellular respiration outputs, and cellular respiration needs oxygen which photosynthesis makes.

How do cellular respiration and photosynthesis compare?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide.

Why is cellular respiration considered aerobic?

The main purpose of cellular respiration is to take glucose (a simple sugar molecule) and break it apart to release energy in the form of ATP. … Cellular respiration is considered an aerobic process because it, as a whole, requires oxygen in order to occur. Because of this, it is also called aerobic respiration.

Why is respiration a better method than fermentation for extracting energy from glucose?

Why is respiration a better method than fermentation for extracting energy from glucose? – Respiration uses up the NADH produced in glycolysis, producing more ATP. … Respiration results in 36 ATP per glucose molecule compared to the two ATP produced by glycolysis followed by fermentation.

Why is cellular respiration more efficient than fermentation quizlet?

Cellular respiration is more efficient at producing ATP than fermentation. Fermentation nets 2 ATP from a glucose molecule; whereas cellular respiration nets 36 ATP. … Without this molecule, cellular respiration does not happen, because it is the final electron acceptor.

Which is more efficient aerobic respiration or fermentation explain your answer?

The most efficient way is through aerobic respiration, which requires oxygen. … Such processes that happen without oxygen are called anaerobic. Fermentation is a common way for living things to make ATP without oxygen.

Why is cellular respiration more efficient than combustion?

Cellular Respiration is the release of energy from food through oxygen. In cellular respiration, energy is released in the form of heat and ATP. It takes place at lower temperatures than Cellular Combustion because it is catalyzed by enzymes.
