What do cells use for cellular respiration?
Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.
For what purpose does a cell use the energy from redox reactions in cellular respiration?
The purpose of cellular respiration is to draw energy, oxygen and also to have carbon dioxide. As part of a cellular reaction, glucose is broken down to release ATP, and energy in the form of ATP is seen as the most important feedback of the cellular respiration.
What are the two main cofactors used in cellular redox reactions?
Nicotinamide adenine dinucleotides, NAD and NADP, are indispensable cofactors involved in several redox reactions in all forms of cellular life.
Is NADH oxidized or reduced in cellular respiration?
In the last phase of cellular respiration, the electron transport chain, FADH2 and NADH are also being oxidized when they give off their gained electrons.
What are examples of cellular respiration?
Types of Cellular Respiration Below are examples of aerobic respiration and anaerobic cellular respiration: lactic acid fermentation and alcoholic fermentation.
What are the types of cellular respiration?
There are two main types of cellular respiration—aerobic respiration and anaerobic respiration. Aerobic respiration is a specific type of cellular respiration, in which oxygen (O2) is required to create ATP.
What is the role of redox reactions in photosynthesis and cellular respiration?
Redox reactions are an important process for cellular respiration and photosynthesis. In respiration, electrons are transferred from glucose molecules to oxygen. Therefore, glucose is oxidized, while oxygen is reduced in cellular respiration. However, in photosynthesis, electrons travel from water to CO2.
What are the examples of redox reaction?
For example, Nitrogen(N2) and hydrogen(H2) in their elemental state will have zero oxidation state. Another example is, in diamond, graphite and buckminsterfullerene carbon has oxidation number ‘0’. The charge present on any monoatomic ion is its oxidation number.
What type of chemical reaction is cellular respiration?
The reactions of cellular respiration are catabolic reactions. In catabolic reactions, bonds are broken in larger molecules and energy is released. In cellular respiration, bonds are broken in glucose, and this releases the chemical energy that was stored in the glucose bonds.
What is oxidised in cellular respiration?
During aerobic respiration, oxygen is reduced, donating an electron to hydrogen to form water. The entire process of cellular respiration oxidizes glucose. This produces the majority of the energy released in cellular respiration.
What type of reaction is respiration?
Respiration is a series of exothermic reactions that occur in the mitochondria of living cells in order to release energy from food molecules. This energy can then be used to produce heat, for movement, growth, reproduction and active uptake. There are 2 types of respiration – aerobic and anaerobic.
What are the 3 types of cellular respiration?
Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. Glycolysis is an anaerobic process. The other two stages are aerobic processes. The products of cellular respiration are needed for photosynthesis, and vice versa.
What are the three reactions of cellular respiration?
Cellular respiration occurs in three distinct, yet inter-connected, series of reactions: glycolysis, citric acid cycle, and the electron transport chain (oxidative phosphorylation).
What reactant in cellular respiration is oxidized?
During aerobic respiration, the oxygen taken in by a cell combines with glucose to produce energy in the form of Adenosine triphosphate (ATP), and the cell expels carbon dioxide and water. This is an oxidation reaction in which glucose is oxidized and oxygen is reduced.
What is the general reaction for cellular respiration?
Cellular respiration is a series of metabolic reactions in which biochemical energy from nutrient is converted into ATP . In cellular respiration glucose and oxygen yield water and carbon dioxide. So, a general reaction could be represented as: glucose + oxygen → carbon dioxide + water + ATP.
Which reactants are involved in cellular respiration?
Most of the steps of cellular respiration take place in the mitochondria.
