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.

    ATP (adenosine triphosphate) is vital to living organisms. It acts as a short-term store of energy in a cell, carrying it from where it is synthesised (e.g. the mitochondria) to where it is needed for biological processes. It is well suited to this job for the following reasons: it is small and soluble (and so can be easily transported around a cell); it is easily broken down to release energy; it can transfer energy to other molecules; and it cannot leave the cell. All of these facts mean that ATP is always available to the cell as an immediate source of energy.…

    Adenosine triphosphate (ATP) is a multifunctional nucleotide used in cells as a coenzyme. It is often called the "molecular unit of currency" of energy transfer. ATP transports chemical energy within cells for metabolism. It is produced by photo-phosphorylation and cellular respiration and used by enzymes and structural proteins in many cellular processes, including active transport, respiration, and cell division. One molecule of ATP contains three phosphate groups, and it is produced by ATP synthase from inorganic phosphate and adenosine diphosphate (ADP). ATP is used is many organisms and also in different ways. Below are a few ways in which ATP is used.…

    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.…

    * In Aerobic glycolysis, glucose or glycogen is broken down to pyruvic acid via glycolitic enzymes during carbohydrate metabolism. Hydrogen is released and glucose is metabolized to pyruvic acid. In the presence of oxygen, the pyruvic acid is converted into acetyl coenzyme A. (Acetyl CoA). 1 mole of glucose produce 2 moles of ATP or 1 mole of glycogen produces 3 moles of ATP.…

    ATP or adenosine triphosphate, is a chemical compound that cells use to store and transfer potential energy. Adenosine triphosphate consists of Adenosine bonded to three negatively charged phosphates these phosphates are bonded close together and their negative charge makes them naturally repel away from each other weakening the bond. The weakness of the bonds between the phosphates is what gives ATP it's great potential energy. Adenosine is a compound of a nitrogen base and a sugar compound, Adenine and Ribose.…

    Cellular respiration a process in which sugar and oxygen are used to produce adenosine triphosphate (ATP), water, and carbon dioxide. The chemical equation for this reaction is C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (ATP). Cellular respiration occurs in 4 steps: Glycolysis, the preparatory reaction, the Krebs Cycle, and the oxidative phosphorylation. Glycolysis occurs in the cytoplasm of the cell, in this process glucose is broken into two 3 Carbon molecules called pyruvates. The preparatory reaction occurs in the matrix of the mitochondria and in this reaction pyruvate get oxidized and attached to a coenzyme. The product is called acetyl CoA which is used to carry out the Krebs Cycle. The Krebs Cycle occurs in the matrix of the mitochondria,…

    ATP synthase (EC 3.6.3.14) is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP). ATP is the most commonly used "energy currency" of cells from most organisms. It is formed from adenosine diphosphate (ADP) and inorganic phosphate (Pi), and needs energy. The overall reaction sequence is: ADP + Pi → ATP, where ADP and Pi are joined together by ATPsynthase Energy is often released in the form of protium or H+, moving down an electrochemical gradient, such as from the lumen into the stroma of chloroplasts or from the inter-membrane space into the matrix in mitochondria.…

    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…
