Is energy gained or lost during cellular respiration?

Is energy gained or lost during cellular respiration?

During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).

Is some energy is lost as heat in photosynthesis and cellular respiration?

Energy from the sun enters a plant and is converted into glucose during photosynthesis. Some of the energy is used to make ATP in the mitochondria during cellular respiration, and some is lost to the environment as heat.

Does aerobic or anaerobic respiration release energy?

With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.

Is more or less energy released during anaerobic respiration?

In anaerobic respiration, less energy is extracted. In this process only 02 ATP molecules are produced by each glucose molecule and the glucose molecules are partially broken down. The reaction yields less energy as compared to the aerobic respiration because the end product is alcohol and not carbon dioxide.

What is the relationship between photosynthesis and aerobic cellular respiration?

What is the relationship between photosynthesis and cellular respiration? Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food.

How is energy released in anaerobic respiration?

Unlike aerobic respiration, anaerobic respiration does not need oxygen. It is the release of a relatively small amount of energy in cells by the breakdown of food substances in the absence of oxygen.

Why does anaerobic respiration release less energy than aerobic?

Anaerobic respiration in muscles Glucose is not completely broken down, so much less energy is released than during aerobic respiration. There is a build-up of lactic acid in the muscles during vigorous exercise. The lactic acid needs to be oxidised to carbon dioxide and water later.

Why does anaerobic respiration occur in the absence of oxygen?

Anaerobic Respiration. Sometimes there is not enough oxygen around for some organisms to respire, but they still need the energy to survive. Due to lack of oxygen, they carry out respiration in the absence of oxygen to produce the energy they require, which is referred to as anaerobic respiration.

How is carbon dioxide produced in aerobic respiration?

Aerobic respiration, as the name suggests, is the process of producing the energy required by cells using oxygen. The by-product of this process produces carbon dioxide along with ATP – the energy currency of the cells.

Where does cellular respiration take place in the body?

Cellular respiration is a process that takes place inside the cells where energy is released by the breakdown of glucose molecules. The process can be conveniently divided into two categories based on the usage of oxygen, namely aerobic and anaerobic respiration.

What is the equation for aerobic cellular respiration?

The equation for aerobic cellular respiration is: C6H12O6 + 6O2 ————–> 6CO2 + 6H2O + ATP
