What is ATP AP biology?

Adenosine triphosphate or ATP is the energy “currency” or carrier of the cell. When cells require an input of energy, they use ATP. An ATP nucleotide molecule consists of a five-carbon sugar, the nitrogenous base adenine, and three phosphate groups.

What is ATP in biology photosynthesis?

ATP is a reservoir of potential chemical energy and acts as a common intermediate in metabolism, linking energy requiring and energy yielding reactions. In photosynthesis energy is transferred to ATP in the light-dependent stage and the ATP is utilised during synthesis in the light-independent stage.

What is ATP quizlet?

Adenosine triphosphate (ATP) a compound composed of adenosine and three phosphate groups that supplies energy for many biochemical cellular processes by undergoing enzymatic hydrolysis.

What is ATP in PE?

The source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) – the body’s biochemical way to store and transport energy. However, ATP is not stored to a great extent in cells. So once muscle contraction starts, the making of more ATP must start quickly.

What is glycolysis AP Bio?

Explanation: Glycolysis is the process that converts glucose to pyruvate. It produces a total of four ATP, but consumes two ATP, for a net yield of two ATP. Glycolysis is not dependent on the presence of oxygen and can occur in either aerobic or anaerobic environments.

What is ATP hydrolysis AP Bio?

ATP structure and hydrolysis The energy released by hydrolysis (breakdown) of ATP is used to power many energy-requiring cellular reactions. The bonds between the phosphate groups are called phosphoanhydride bonds, and you may hear them referred to as “high-energy” bonds.

How is ATP made in photosynthesis?

This is accomplished by the use of two different photosystems in the light reactions of photosynthesis, one to generate ATP and the other to generate NADPH. Electrons are transferred sequentially between the two photosystems, with photosystem I acting to generate NADPH and photosystem II acting to generate ATP.

How is ATP used in photosynthesis and cellular respiration?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

What is the role of ATP in the human body quizlet?

ATP stands for adenosine triphosphate. It is a molecule found in the cells of living organisms. It is said to be very important because it transports the energy necessary for all cellular metabolic activities. It is dubbed as the universal unit of energy for living organisms.

What is ATP and how is it used quizlet?

ATP is used by cells to perform useful ‘work’. ATP (adenosine triphosphate) – as the name suggests, has three phosphate groups. The bond between these groups are unstable and so have a low activation energy which means they are easily broken. When the bonds break they release a considerable amount of energy.

How is ATP produced during exercise?

When muscles exhaust their stores of readily available ATP and phosphocreatine, the next fuel of choice is glucose, either from blood sugar or the muscle’s own glycogen. Glucose is quickly mobilized to produce ATP to power the muscles and allow activity to continue.

What is glycolytic energy system?

The glycolytic system, or anaerobic glycolysis, is the second of three energy-producing systems in our bodies, following the creatine phosphate system. It relies on carbohydrates as a fuel source to make energy. The glycolytic energy system is one you rely on during any sort of physical activity.

What is an ATP molecule?

Adenosine triphosphate, or ATP, is a small, relatively simple molecule. It can be thought of as the main energy currency of cells, much as money is the main economic currency of human societies.

What is adenosine triphosphate (ATP)?

Adenosine triphosphate, also known as ATP, is a molecule that carries energy within cells. It is the main energy currency of the cell, and it is an end product of the processes of photophosphorylation (adding a phosphate group to a molecule using energy from light), cellular respiration, and fermentation.

What is the function of ATP in cell communication?

ATP is a signaling molecule used for cell communication. Kinases, which are enzymes that phosphorylate molecules, use ATP as a source of phosphate groups. Kinases are important for signal transduction, which is how a physical or chemical signal is transmitted from receptors on the outside of the cell to the inside of the cell.

What is the difference between ADP and ATP cycle?

Image of the ATP cycle. ATP is like a charged battery, while ADP is like a dead battery. ATP can be hydrolyzed to ADP and Pi by the addition of water, releasing energy. ADP can be “recharged” to form ATP by the addition of energy, combining with Pi in a process that releases a molecule of water.
