Question

1. Draw and label the parts of an ATP and ADP molecule. . 2. Explain (in diagrams) how energy can be \"stored\" using ADP and a phosphate group.. . 3. Use diagrams to illustrate how energy is released from ATP molecules.. . 4. What is \"left over\" when energy is released from ATP?.

Answer 1

Answer:

• ATP(adenine tri-phosphate):

A form of nucleotide which is also some times refereed as energy currencies in bio-chemical processes. As the energy is stored in the coins like structures(thylakoid), which is then utilized to drive any process.The ATP provides the energy in a dynamic form, as the structures which holds the stored energy needs the energy to drive the cellular functions.

Structure:

ATP is a form of nucleotide structure which is mainly responsible for providing or driving the energy present in stored form from one point to another, through various chemical reactions.( Metabolic pathways).

It is mainly composed of three parts:

1. A nitrogenous base, adenine,
2. The sugar molecule, ribose.
3. A chain of three phosphate group.

• ADP(adenosine di-phosphate)

Its is also a nucleotide but compared to ATP, it has one phosphate group less in its structure. The dynamic energy released from its hydrolysis is compensated in contraction of the muscles, along with that it also helps in the healing process if the blood vessels are damaged or breached.

Explanation:

Now, the ATP molecule has a head and tail, the tail posses the total amount of energy required to drive the processes or simply the bio-chemical processes which occurs on cellular level.

Through hydrolysis the molecule is broken down into the energy required to drive the process.

The rest of the diagrammatic process is given in the diagrams provided below,as:

Answer 2

Adenosine triphosphate (ATP) consists of an adenosine molecule bonded to three phophate groups in a row. 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. This occurs when a molecule of adenosine diphosphate (ADP) uses the energy released during cellular respiration to bond with a third phosphate group, becoming a molecule of ATP. So the energy from cellular respiration is stored in the bond between the 2nd and 3rd phosphate groups of ATP. When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work. Now its back to being ADP and is ready to store the energy from respiration by bonding with a 3rd phosphate group. ADP and ATP constantly convert back and forth in this manner.
