1. What two molecules are formed when a phosphate is removed from ATP?

There are three phosphate groups in ATP molecule (Adenosine Triphosphate), when removing one phosphate molecule, ADP molecule is formed (Adenosine Diphosphate).

2. What is the function of ATP? Describe the molecule.

The function of ATP is storing energy within a cell. ATP is adenosine triphosphate, C10H16N5O13P3, a high energy complex, giving the necessary power to push metabolistic reactions in the body. Its composed of adenosine, a ribose sugar, and three phosphates.

3. Describe how ADP is converted into ATP.

By adding one phosphate molecule to ADP, it becomes ATP.

4. Differentiate between oxidation and reduction reactions.

Oxidation is a process, in which the atom or ion is increasing its oxidation sate. This will result in loss of electrons. The species that are being oxidized, are the reduction agents. Reduction is a process, by which the atom or ion is decreasing its oxidation state. This will result in a gain of electrons. Here, the species that are being reduced are the oxidizing agents.

5. Why is an electron transport system important to living organisms?

Because it releases energy from fuel in a slow and controlled fashion.

6. Why are oxidation reactions often associated with the production of ATP?

They release energy, thus helping with the production of ATP.

7. In the reaction ADP + P forms ATP is energy stored or released?

Stored , because with the addition of a Phosphate molecule ATP is formed.

8. The primary source of energy for the cell is (a) starch (b) cellulose (c) glucose (d) ATP (e) sunlight

© Glucose

9. Why must glycolysis occur before the steps of aerobic respiration can begin?

Glycolysis breaks glucose into two pyruvate molecules, to be broken down in the citric-acid cycle. For this reason, it must occur before the steps of aerobic respiration can begin.

10. What is the

    1. What is the difference between an oxidizing agent and a reducing agent? The oxidation number (overall charge of the atom) is reduced in reduction and this is accomplished by adding electrons. The electrons, being negative, reduce the overall oxidation number of the atom receiving the electrons. Oxidation is the reverse process: the oxidation number of an atom is increased during oxidation. This is done by removing electrons. The electrons, being negative, make the atom that lost them more positive…

    Stage one glycolysis means the “splitting of sugar”. Glycolysis is a six carbon glucose molecule which is then broken in half, forming two three carbon molecules. The initial split requires an energy investment of two ATP molecules per glucose. Then the three carbon molecules donate high energy electrons to NAD+, the electron carrier forming NADH. Glycolysis then makes four ATP molecules when the enzymes transfer phosphate groups from fuel molecules to ADP. Glycolysis produces a net of two molecules of ATP per molecule of glucose. Then the pyruvic acid holds most of the energy of glucose and that energy is then harvested for stage two.…

    Glycolysis is where glucose is split into two molecules of 3-carbon sugars. This produces 2ATP, 2 pyruvic acid, and 2 high energy. In The Citric Acid Cycle, Acetyl CoA is created. NAD and FAD are reduced carrying the high energy electrons to the next stage. In the Electron Transport, high energy electrons are passed to oxygen where ATP is then produced.…

    Living organisms including all plants and animals require energy for their cellular processes. In biological processes, the immediate energy source is often in the form adenosine triphosphate (ATP). The nucleotide ATP maintains both catabolic and anabolic reactions. An example of a catabolic reaction is respiration where large molecules are broken down into smaller ones with energy released. An example of an anabolic reaction is photosynthesis where small molecules are built up into larger ones using energy. ATP is built up from ADP and inorganic phosphate ions (3-4 PO, abbreviated to Pi) by condensation and is then hydrolysed by the enzyme ATPase to ADP and Pi to release energy that can be used for energy requiring reactions such as photosynthesis in plants.…

    Cellular respiration is a three part process which includes glycolysis, Kreb's cycle, and oxidative phosphorylation. In glycolysis glucose is broken down in a ten step process into 2 3-carbon pyruvate molecules. During glycolysis a net gain of 2 ATP is formed. NAD+ is reduced to NADH and 2H+ ions which in turn go to the oxidative phosphorylation process. After glycolysis, the 2 pryuvate molecules enter the Kreb's cycle. In the presence of oxygen, acetyl-CoA are formed through…
