Which respiratory substrate gives maximum energy?
The maximum amount of energy is obtained by the the oxidation of fat. Explanation: the amount of energy which is liberated by the oxidation of fat is almost double than the energy which is obtained by the oxidation of proteins and carbohydrate.
What substrate produces the most energy?
Carbohydrate and fatty acids are major energetic substrates, although amino acid oxidation also permits ATP synthesis.
Is ATP a respiratory substrate?
Respiratory substrates are the organic nutrients oxidized at the time of respiration. At the time of cellular respiration, oxidation of organic nutrients occurs to obtain energy (ATP).
How many ATP or energy are yield throughout cellular respiration?
Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
Which one of the following gives maximum energy in metabolic processes *?
Lipids (oil or fats) gives maximum energy in the metabolic process.
What are the main source of energy for cell activities?
The immediate source of energy for most cells is glucose. But glucose is not the only fuel on which cells depend. Other carbohydrates, fats and proteins may in certain cells or at certain times be used as a source of ATP.
Which produces the most ATP?
The electron transport chain
Explanation: The electron transport chain generates the most ATP out of all three major phases of cellular respiration. Glycolysis produces a net of 2 ATP per molecule of glucose.
How much ATP does aerobic respiration produce?
Aerobic vs anaerobic respiration
| Aerobic | |
|---|---|
| Products | ATP, water, CO 2 |
| Location | Cytoplasm (glycolysis) and mitochondria |
| Stages | Glycolysis (anaerobic), Krebs cycle, oxidative phosphorylation |
| ATP produced | Large amount (36 ATP) |
What is respiratory substrate?
Answer: Respiratory substrates are those organic substances which are oxidised during respiration to liberate energy inside the living cells. The common respiratory substrates are carbohydrates, proteins, fats and organic acids. The most common respiratory substrate is glucose.
What are the respiratory substrates give one example?
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.
Why is the actual ATP yield of aerobic respiration often less than the maximum possible yield of 38 ATP?
Why is the actual ATP yield of aerobic respiration often less than the maximum possible yield of 38 ATP? Glycolysis cannot occur in an anaerobic environment. Nitrogen is fixed to ammonia by cyanobacteria and other microbes.
Which process is responsible for the largest amount of ATP production during cellular respiration?
Glycolysis takes place in the cytoplasm, whereas the Krebs cycle and the electron transport chain, which generate the largest amounts of ATP during cellular respiration, take place in the mitochondria.
