Which of the following molecules act as an immediate source of energy for cellular work?

The immediate source of energy for most cells is glucose. But glucose is not the only fuel on which cells depend. Other carbohydrates, fats and proteins may in certain cells or at certain times be used as a source of ATP.

Which of the following molecules act as an immediate source of energy for cellular work quizlet?

Terms in this set (15) Adenosine triphosphate (ATP) is the molecule that acts as the immediate source of energy, which drives ALL functions of a cell. When the bond between the last 2 phosphate groups of ATP breaks, a new molecule called Adenosine Diphosphate (ADP) is formed and energy is released.

Which molecule can be used as an immediate source of energy?

A single molecule of glucose stores more than 90 times the energy stored by ATP. However, ATP, which transfers energy quickly, is used by the cell as an immediate source of energy.

IT\'S FUNNING:  When did Louisville Ky get electricity?

What is the source of energy for most cellular work?

ATP is the main source of energy for most cellular processes. The building blocks of ATP are carbon, nitrogen, hydrogen, oxygen, and phosphorus. Because of the presence of unstable, high-energy bonds in ATP, it is readily hydrolyzed in reactions to release a large amount of energy.

Which of the following molecules can be used for sources of cellular energy?

The only form of energy a cell can use is a molecule called adenosine triphosphate (ATP). Chemical energy is stored in the bonds that hold the molecule together. ADP can be recycled into ATP when more energy becomes available. The energy to make ATP comes from glucose.

Which of the following molecules is Catabolized first for an immediate source of energy?

As an immediate source of energy, glucose is broken down during the process of cellular respiration, which produces adenosine triphosphate (ATP), the energy currency of the cell.

What is the source of energy for regenerating ATP from ADP?

Energy derived from glucose catabolism is used to convert ADP into ATP. When ATP is used in a reaction, the third phosphate is temporarily attached to a substrate in a process called phosphorylation.

What is immediate energy source?

The immediate source of energy for most cells is glucose. … Other carbohydrates, fats and proteins may in certain cells or at certain times be used as a source of ATP.

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.

IT\'S FUNNING:  When did electric refrigerators become common?

Which of the following is the immediate source of energy used in homeostasis?

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.

What is the immediate effect for a cell that Cannot obtain glucose?

The cells need energy, and if they can’t get it from sugar, they will get it from other parts of the cell — usually a protein. Not only does the waste product of burning protein lead to a problem called ketoacidosis, but it can also damage the liver and kidneys.

What is our main source of energy?

Our energy supply comes mainly from fossil fuels, with nuclear power and renewable sources rounding out the mix. These sources originate mostly in our local star, the Sun.

Is the source of most of the cellular energy?

As it happens, more specifically, a single molecule of a type of carbohydrate classified as a sugar is the ultimate source of fuel in any metabolic reaction occurring in any cell at any time. That molecule is glucose, a six-carbon molecule in the form of a spiky ring.
