Which of the following provide an immediate source of energy?

The immediate source of energy for most cells is glucose.

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 the immediate source of energy for cells?

ATP is the immediate source of energy in a cell – the more ATP that is produced, the more energy a cell has.

Is ATP an immediate source of energy?

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 energy source for living things?

The breakdown of sugars, such as glucose, supplies immediate energy for cell activities. Plants, some animals, and other organisms also use carbohydrates for structural purposes.

What is immediate source of energy quizlet?

An ATP molecule consists of a nitrogen containing compound called adenine and three phosphate groups. … A Single molecule of glucose stores more than 90 times the energy stored by ATP. ATP transfers energy quickly and is used by the cell as an immediate source of energy.

Is the instant source of energy?

-Glucose is absorbed directly by cells and used in glycolysis. … Hence, glucose is termed as an instant source of energy.

What is the immediate source of energy for active transport?

Verified Answer. The immediate energy for active transport is obtained from the ATP molecules. Both direct and indirect method uses the ATP to transport the molecules.

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.

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.

Why is ATP a good immediate energy source?

The energy-containing phosphate bond is easily broken down to release the energy it holds and to further this ATP molecules are not lipid soluble and therefore they are unable to pass beyond the cell membrane, ensuring the cell always always has an immediate energy source.

Which of the following substances is the immediate energy source of a working cell?

Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.

What is the immediate source of energy used to synthesize ATP by oxidative phosphorylation?

During oxidative phosphorylation, electrons derived from NADH and FADH2 combine with O2, and the energy released from these oxidation/ reduction reactions is used to drive the synthesis of ATP from ADP.

What is the immediate source of energy for animals?

The primary source of energy for animals is carbohydrates, primarily glucose: the body’s fuel. The digestible carbohydrates in an animal’s diet are converted to glucose molecules and into energy through a series of catabolic chemical reactions. Adenosine triphosphate, or ATP, is the primary energy currency in cells.

What macromolecule provides energy?

Carbohydrates are a group of macromolecules that are a vital energy source for the cell, provide structural support to many organisms, and can be found on the surface of the cell as receptors or for cell recognition.

Which compound in the body is the most immediate source of glucose?

Glycogen is a glucose polysaccharide occurring in most mammalian and nonmammalian cells, in microorganisms, and even in some plants. It is an important and quickly mobilized source of stored glucose. In vertebrates it is stored mainly in the liver as a reserve of glucose for other tissues.
