What process converts glucose and oxygen into ATP?
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP.
What is the process in which glucose and oxygen is turned into energy it occurs in the mitochondria?
Mitochondria (singular: mitochondrion) convert chemical energy into energy that our cells can actually use. This process is called cellular respiration. The mitochondria use it to turn glucose and oxygen into a high-energy molecule called ATP.
What is the process of converting glucose to energy in the absence of oxygen?
Glycolysis is a linear metabolic pathway of enzyme-catalyzed reactions that converts glucose into two molecules of pyruvate in the presence of oxygen or two molecules of lactate in the absence of oxygen.
Which process turns glucose into energy?
cellular respiration
Once glucose is digested and transported to your cells, a process called cellular respiration releases the stored energy and converts it to energy that your cells can use. Cellular respiration consists of three metabolic processes: glycolysis, the Krebs cycle, and oxidative phosphorylation.
How does oxygen break down glucose?
Aerobic respiration Glucose is oxidised to release its energy, which is then stored in ATP molecules. Aerobic respiration breaks down glucose and combines the broken down products with oxygen, making water and carbon dioxide. The carbon dioxide is a waste product of aerobic respiration because cells do not need it.
What does oxygen do for cellular respiration?
How is oxygen used in cellular respiration? Oxygen is used as the end electron acceptor for the electron transport chain in cellular respiration. It allows electrons to be transferred through the electron transport chain in order to create an electrochemical gradient for hydrogen to create ATP.
When does the cell use oxygen to break down sugar?
During cellular respiration the cell uses oxygen to break down sugar. When the cell uses oxygen to break down sugar, oxygen is used, carbon dioxide is produced, and energy is released. In which process are glucose and oxygen the reactants?
Where does the energy for cellular processes come from?
Cellular processes such as the building and breaking down of complex molecules occur through stepwise chemical reactions. Some of these chemical reactions are spontaneous and release energy, whereas others require energy to proceed. Figure 1. Ultimately, most life forms get their energy from the sun.
How is the energy released from ATP used?
The energy is used to do work by the cell, usually by the released phosphate binding to another molecule, activating it. For example, in the mechanical work of muscle contraction, ATP supplies the energy to move the contractile muscle proteins.
Where does the energy from photosynthesis come from?
During photosynthesis, plants use energy (originally from sunlight) to convert carbon dioxide gas (CO 2) into sugar molecules (like glucose: C 6 H 12 O 6 ). They consume carbon dioxide and produce oxygen as a waste product.
