The process of using glucose to make energy is called cellular respiration. The reactants, or what we start with, in cellular respiration are glucose and oxygen. We get oxygen from breathing in air. Our bodies do cellular respiration to make energy, which is stored as ATP, and carbon dioxide.

Answer: Food that we eat serves as the source of reactant for the process of cellular respiration. Cellular respiration can be defined as the biological process which uses glucose as reactant to convert into carbon dioxide and water.

Most of the steps of cellular respiration take place in the mitochondria. Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

Aerobic vs anaerobic respiration

Cellular respiration

Glycolysis is a series of reactions that extract energy from glucose by splitting it into two three-carbon molecules called pyruvates.

Explain how glycolysis releases free energy from glucose. Glycolysis uses substrate level phosphorlyation to make ADP into ATP as phosphates from glucose intermediate are transferred by an enzyme to ADP . The excess energy made by the metabolism of glucose is released as heat.

Energy is stored in the chemical bonds of the glucose molecules. Once glucose is digested and transported to your cells, a process called cellular respiration releases the stored energy and converts it to energy that your cells can use.

During glycolysis, one glucose molecule is split into two pyruvate molecules, using 2 ATP while producing 4 ATP and 2 NADH molecules.

Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain.

Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.

Aerobic respiration and fermentation are two processes which are used to provide energy to cells. In aerobic respiration, carbon dioxide, water, and energy in the form of adenosine triphosphate (ATP) is produced in the presence of oxygen. Fermentation is the process of energy production in the absence of oxygen.

Krebs cycle (or Citric acid cycle) This breaks down the pyruvic acid to carbon dioxide. This produces 2 ATP and 6 NADH , for every glucose molecule entering glycolysis. The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out.

Listen to pronunciation. (ayr-OH-bik RES-pih-RAY-shun) A chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also called aerobic metabolism, cell respiration, and oxidative metabolism.

2 major events of aerobic respiration are: Glycolysis and Kreb’s cycle which occur in cytoplasm and mitochondria respectively. Aerobic respiration is the cellular process in which glucose is broken down into carbon dioxide and water in the presence of oxygen and large amounts of ATP is released.

Hence, we can conclude that the main steps involved in Aerobic Respiration are Glycolysis, Link reaction, and Kreb’s cycle. Also, Glycolysis occurs in the matrix of the cytoplasm, whereas Link reaction and Kreb’s cycle occurs in the matrix of the mitochondria.

In aerobic conditions, the process converts one molecule of glucose into two molecules of pyruvate (pyruvic acid), generating energy in the form of two net molecules of ATP. Four molecules of ATP per glucose are actually produced, however, two are consumed as part of the preparatory phase.

mitochondria

Respiration occurs in the mitochondria of the cell of the human body. Breathing occurs through lungs.

The most common respiratory substrate in the body is glucose. – One molecule of glucose gives 38 molecules of ATP, hence it is an instant source of energy. – It is also abundantly available and is stored easily in the body in the form of glycogen. It is also stored in plants in the form of starch or complex sugars.

During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.

Aerobic cellular respiration rates vary according to three main factors: the amount of nutrients available to the cell, the specific type of cell and the ambient temperature. All three factors affect the rate at which respiration takes place.

The eight environmental factors effecting the rate of respiration are: (1) Oxygen Content of the Atmosphere (2) Effect of Temperature (3) Effect of Light (4) Effect of Water Contents (5) Effect of Respirable Material (6) Effect of Carbon Dioxide Concentration (7) Protoplasmic Conditions and (8) Other Factors.

Explanation: The increase in temperature enhances the rate of cellular respiration. It means reactions speed up and rate of cellular respiration increases. When temperature decreases, in order to conserve energy, cellular processes slow.

If the temperature goes too high, the enzymes responsible for cellular respiration will denature. This will result in the reaction going slower (as more of the enzyme molecules denature). Eventually, high enough temperatures will denature all of the enzymes and the reactions will stop completely.

As animals respire, heat is also released. In birds and mammals, this heat is distributed around the body by the blood. It keeps these animals warm and helps to keep a constant internal temperature. to maintain constant conditions in cells and the body – homeostasis .

Respiration: The act of inhaling and exhaling air in order to exchange oxygen for carbon dioxide.

What is another word for respiration?

the act of respiring; inhalation and exhalation of air; breathing. Biology. the sum total of the physical and chemical processes in an organism by which oxygen is conveyed to tissues and cells, and the oxidation products, carbon dioxide and water, are given off.
