How are ATP molecules produced?
Most of the ATP in cells is produced by the enzyme ATP synthase, which converts ADP and phosphate to ATP. The three processes of ATP production include glycolysis, the tricarboxylic acid cycle, and oxidative phosphorylation. In eukaryotic cells the latter two processes occur within mitochondria.
Does oxygen break down 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….Aerobic vs anaerobic respiration.
| Aerobic | Anaerobic | |
|---|---|---|
| Reactants | Glucose and oxygen | Glucose |
What molecules are broken down into ATP?
ATP is a nucleotide consisting of an adenine base attached to a ribose sugar, which is attached to three phosphate groups. These three phosphate groups are linked to one another by two high-energy bonds called phosphoanhydride bonds.
Is the breakdown of sugars to make ATP in the absence of oxygen?
Digestion is the breakdown of carbohydrates to yield an energy rich compound called ATP. When oxygen is absent, the generation of ATP continues through fermentation. There are two types of fermentation: alcohol fermentation and lactic acid fermentation.
What three main things make up an ATP molecule?
The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.
Which process is responsible for ATP molecule energy release?
cellular respiration
In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP.
How does oxygen affect cellular respiration?
Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. 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.
What is the main role of oxygen in cellular respiration?
Oxygen plays a vital role in energy production via a system called electron transport chain (ETC), which is an important component of cellular respiration. Oxygen acts as a final electron acceptor that helps move electrons down a chain that results in adenosine triphosphate production.
How are ATP produced during this final stage of respiration?
ATP synthase pumps, by active transport, hydrogen ions back into the mitochondria matrix. Electron transport is the final stage of aerobic respiration. In this stage, energy from NADH and FADH2, which result from the Krebs cycle, is transferred to ATP.
What bond must be broken for ATP to release energy?
ATP is the “stored” energy form, which can release energy by breaking a chemical bond between the last two (2) phosphate groups, thus becoming ADP.
