what are respiratory substrates give one example?
499
Respiratory substrate. The substance required for cellular respiration to derive energy through oxidation. Carbohydrates, fats, and proteins are examples of respiratory substrates. The most common among them is carbohydrates, especially glucose.

In prokaryotes, forms of glycolysis and the citric acid cycle are carried out in the absence of mitochondria. Another form of substrate-level phosphorylation is also seen in working skeletal muscles and the brain. ... Substrate-level phosphorylation can also be observed in fermentation.

In biochemistry, the substrate is a molecule upon which an enzyme acts. Enzymes catalyze chemical reactions involving the substrate(s). In the case of a single substrate, the substrate bonds with the enzyme active site, and an enzyme-substrate complex is formed.

Steps of cellular respiration. Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

In aerobic respiration, the main form of cellular respiration used by humans, glucose and oxygen are metabolized to release energy, with carbon dioxide and water as byproducts.

A number of molecules can act as electron carriers in biological systems. In cellular respiration, there are two important electron carriers, nicotinamide adenine dinucleotide (abbreviated as NAD+ in its oxidized form) and flavin adenine dinucleotide (abbreviated as FAD in its oxidized form).

Cellular respiration can be an anaerobic or aerobic respiration, depending on whether or not oxygen is present. Anaerobic respiration makes a total of 2 ATP. Aerobic respiration is much more efficient and can produce up to 38 ATP with a single molecule of glucose.
88663
Aerobic respiration needs oxygen to occur, while anaerobic does not. This presence of oxygen determines what products will be created. During aerobic respiration, carbon dioxide, water, and ATP are produced. During anaerobic respiration, lactic acid, ethanol, and ATP are created.

The similarities between aerobic and anaerobic respiration, is that they both use glucose as the starting molecule. This is called the substrate. ... This means that glucose goes through different processes in anaerobic and aerobic respiration, thus producing a difference in the amount of ATP.

Respiration using oxygen to break down food molecules is called aerobic respiration . 'Aero' means air, which contains oxygen, leading to the name aerobic respiration. Glucose is the molecule normally used for respiration - it is the main respiratory substrate .

The raw materials required for the cell to produce one molecule of ATP via substrate-level phosphorylation are ADP, Pi (or a phosphate-containing intermediate from glucose), and a substrate enzyme. 2. (a) Glycolysis occurs in the cytoplasm of eukaryotic organisms.

Living organisms use energy released by respiration for their life processes. There are two types of respiration – aerobic (which needs oxygen) and anaerobic (which doesn't need oxygen).
