Explanation: ATP (Adenosine Triphosphate) is a more immediate source of energy than glucose because ATP is produced in the cells and its conversion to energy is a single-step process. Whereas glucose first needs to be broken down in order to be used as an energy source.
What is the immediate source of energy?
Glucose is the immediate source of energy.
What is the most immediate source of energy in the body?
Carbohydrates, such as sugar and starch, for example, are readily broken down into glucose, the body’s principal energy source. Glucose can be used immediately as fuel, or can be sent to the liver and muscles and stored as glycogen.
What is used as an immediate source of energy in cells?
ATP is the immediate source of energy in a cell – the more ATP that is produced, the more energy a cell has.
Why is ATP an intermediate energy source?
All organisms need energy. Life depends on the transfer of energy. … Energy is transferred from molecules such as glucose, to an intermediate energy source, ATP. ATP is a reservoir of potential chemical energy and acts as a common intermediate in metabolism, linking energy requiring and energy yielding reactions.
How is ATP used as an energy source?
ATP is able to power cellular processes by transferring a phosphate group to another molecule (a process called phosphorylation). This transfer is carried out by special enzymes that couple the release of energy from ATP to cellular activities that require energy.
Why is ATP better than glucose as an immediate energy source for cell metabolism?
It is much more energy efficient to add and remove those phosphate groups than to add and subtract elements from a glucose molecule, as there is no way to effectively break it down without significantly changing its structure, which makes it harder to build back up.
What is immediate source of energy for an athlete?
Carbohydrate provides an immediate source of energy for an athlete. When an athlete starts his work, his body uses the available glucose as the source of energy. When the level of glucose gets reduced, the stored form of glucose which is called glycogen comes into action.
Is the source of ATP in aerobic activities?
Although the primary source of ATP in aerobic metabolism is carbohydrates, fatty acids and protein can also be used as fuel to generate ATP.
How does ATP store and release energy?
ATP (adenosine triphosphate) stores energy in its high energy phosphate bonds. … When the cells need energy to do any work, ATP cleaves the third phosphate group, releasing a large amount of energy stored in the bond between the third and second phosphate group.
What is the immediate source of energy for muscle contraction?
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.
Which of the following is used by cells as an immediate source of energy for cellular work quizlet?
ATP transfers energy quickly and is used by the cell as an immediate source of energy.
Is ATP a energy?
Adenosine 5′-triphosphate, or ATP, is the principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank.
How is energy released from ATP quizlet?
The energy released by ATP is released when a phosphate group is removed from the molecule. … When phosphate is removed, energy is released and ATP becomes ADP.
Why is ATP a universal energy currency?
ATP is referred to as currency because it can be “spent” in order to make chemical reactions occur. The more energy required for a chemical reaction, the more ATP molecules must be spent. Virtually all forms of life use ATP, a nearly universal molecule of energy transfer.
