mitochondria
Chemical energy is the energy stored in a substance due to its chemical composition. This energy is released when chemical reactions occur.
The substance that stores energy is called adenosine triphosphate (ATP). ATP is the primary molecule used by cells to store and transfer energy within the cell.
Energy in a substance is stored in the bonds between its atoms or molecules. When these bonds are broken, energy is released or absorbed. This energy can be in the form of potential energy (stored energy) or kinetic energy (energy of movement).
The enthalpy of fusion is the heat energy absorbed or released when a substance changes from solid to liquid at its melting point. The enthalpy of vaporization is the heat energy absorbed or released when a substance changes from liquid to gas at its boiling point.
When energy is released, it causes the molecules in a substance to move faster and increase in temperature. This can be due to processes like chemical reactions, nuclear reactions, or friction generating heat energy. The sensation of heat is a result of the increased molecular motion in the substance.
ATP is a substance that stores energy released by mitochondria.
Glucose
Kinetic energy
Energy of glucose is released. This energy is stored in ATP
glucose
When a substance is cooled to its original temperature, no energy is released. Cooling a substance typically involves removing energy from the substance, but this process does not generate energy. The energy removed is used to lower the temperature of the substance.
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
ATP (adenosine triphosphate) is the substance that is made from the energy released from broken carbohydrate bonds during cellular respiration. ATP is the primary energy currency in cells and is used to power various cellular processes.
Mitochondria provide eukaryotic cells with energy. Mitochondria are the power house of the cell, their energy is made by combining the sugar-like substance called cristae and oxygen, creating ATP.
