Q:

What are the end products of cellular respiration?

A:

Quick Answer

The end products of cellular respiration are adenosine triphosphate, or ATP, molecules that the cell uses for a variety of processes. Cellular respiration yields 38 ATP molecules in prokaryotes and 36 ATP molecules in eukaryotes.

Full Answer

Cellular respiration is a method for cells to obtain the energy that is stored in food. It takes place in three stages: glycolysis, the citric acid cycle and electron transport. Some stages of the process require oxygen while some do not. Eukaryotic cells produce two fewer ATP molecules than prokaryotic cells during cellular respiration due to the passing of NADH molecules from glycolysis through the mitochondrial membrane.

  • Q:

    During what part of aerobic respiration is the majority of ATP produced?

    A:

    The majority of adenosine triphosphate (ATP) molecules are produced during the electron transport chain. This is part of the final step in aerobic cell respiration and part of the oxidative phosphorylation process.

  • Q:

    What do mitochondria give off during cellular respiration?

    A:

    Mitochondria give off water, carbon dioxide and energy, in the form of ATP molecules, during cellular respiration. Mitochondria produce these by combining glucose and oxygen molecules, which creates the molecules and releases large amounts of energy. This is the main process by which most organisms meet their energy needs.

  • Q:

    What does cellular respiration produce?

    A:

    Cellular respiration produces molecules of adenosine triphosphate, or ATP, an organic compound composed of adenine, the sugar ribose and three phosphate groups. ATP is a high-energy molecule that cells use to drive many biological processes requiring energy. It is vital to the majority of cellular functions.

  • Q:

    What is responsible for making ATP?

    A:

    Adenosine triphosphate (ATP) is created in organisms through the processes of photosynthesis, glycolysis, cellular respiration and fermentation. Photosynthesis and fermentation are restricted to plants and fungi, respectively, but glycolysis and respiration occur in both plant and animal cells.
