What is the main source of energy for cellular respiration carbohydrates?

The energy from glucose comes from the chemical bonds between the carbon atoms. Sunlight energy was required to produce these high-energy bonds in the process of photosynthesis. Cells in our bodies break these bonds and capture the energy to perform cellular respiration.

What is the main energy source of cellular respiration?

The glucose molecule is the primary fuel for cellular respiration.

What carbohydrate is used in cellular respiration?

In the cells, glucose, a six-carbon sugar, is processed through a sequence of reactions into smaller sugars, and the energy stored inside the molecule is released. The first step of carbohydrate catabolism is glycolysis, which produces pyruvate, NADH, and ATP.

What is the main source of energy for cellular respiration quizlet?

The main source of energy in cellular respiration is glucose.

What happens to carbohydrates during cellular respiration?

What happens to carbohydrates during cellular respiration? They are broken down and they release the energy. It’s also used to combine ADP with another phosphate group to form ATP.

How do carbohydrates provide energy?

When you eat carbs, your body breaks them down into simple sugars, which are absorbed into the bloodstream. As the sugar level rises in your body, the pancreas releases a hormone called insulin. Insulin is needed to move sugar from the blood into the cells, where the sugar can be used as a source of energy.

Are carbohydrates the main source of energy for living things?

Summary. Carbohydrates represent the predominant source of energy for plants and animals.

Where cells obtain energy from carbohydrates?

Animals and other organisms obtain the energy available in carbohydrates through the process of cellular respiration. Cells take the carbohydrates into their cytoplasm, and through a complex series of metabolic processes, they break down the carbohydrates and release the energy.

What is our main source of energy?

Our energy supply comes mainly from fossil fuels, with nuclear power and renewable sources rounding out the mix. These sources originate mostly in our local star, the Sun.

What is the source of the energy in respiration?

The source of the energy required to regenerate ATP is the chemical energy stored in food (e.g. glucose). The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration . Some of the energy released is used to produce ATP.

What are the energy sources in cellular respiration and photosynthesis?

Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.

What is the main energy currency of a cell?

Adenosine 5′-triphosphate, or ATP, is the principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank.

How organism obtain energy from food through cellular respiration?


  1. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells.
  2. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.

What happens during cellular respiration?

cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
