How does the body utilize ATP glycogen during physical activity?
During physical activity, the body uses ATP (adenosine triphosphate) stored in muscles for immediate energy. If the activity continues, the body breaks down glycogen stored in the muscles and liver to produce more ATP for sustained energy.
What pathways break down fuels from the food you eat and the liquids you drink?
The main pathways that break down fuels from food and drink are glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation in the mitochondria. These pathways involve the breakdown of carbohydrates, fats, and proteins to produce energy in the form of ATP.
How do muscles produce heat in the body?
Muscles produce heat in the body through a process called cellular respiration. During this process, glucose is broken down in the presence of oxygen to produce energy in the form of ATP. Some of this energy is released as heat, which helps to maintain the body's temperature.
What are the key differences in the metabolic pathways of glucose and pyruvate?
The key differences in the metabolic pathways of glucose and pyruvate are that glucose is broken down through glycolysis to produce pyruvate, which can then enter the citric acid cycle to produce energy in the form of ATP. Pyruvate, on the other hand, can be converted into acetyl-CoA before entering the citric acid cycle. Additionally, pyruvate can also be converted into lactate or ethanol through fermentation pathways.
Fermentation occurs when a cell does not get enough what?
Fermentation occurs when a cell does not get enough oxygen to carry out aerobic respiration. Instead, the cell uses anaerobic pathways to produce energy in the form of ATP.
Which pathways in photosynthesis will produce ATP but not NADPH?
non-cyclic electron pathways
During a race how do your muscles produce ATP after the store of ATP in muscles is used?
muscle cells produce ATP by cellular respiration through fermentation
Where do cardiac muscles produce ATP?
Cellular respiration
Why do muscles contain many mioochondria?
Muscles need ATP to contract. Mitochondria produce most of the ATP in the cell, so there are lots of mitochondria in muscle.
The cyclic pathways of photosynthesis produce?
The cyclic pathways of photosynthesis produce ATP (adenosine triphosphate) through the process of cyclic photophosphorylation. This pathway involves the movement of electrons through the photosystem I in a cyclic manner, leading to the formation of ATP as an energy carrier for the cell.
Why does exercise generate Hydrogen ions?
During exercise, muscles produce energy through various metabolic pathways, such as glycolysis and the citric acid cycle. These pathways generate adenosine triphosphate (ATP) for muscle contractions, resulting in the production of hydrogen ions as byproducts. This can lead to an increase in acidity in the muscle cells, contributing to muscle fatigue.
Why muscles must have blood pumped to them?
because in order to keep functioning your muscles need oxygen that carried by the blood, to produce ATP.
How does energy get converted from food molecules to muscles?
When we eat food, our body breaks down the molecules through digestion to produce energy in the form of adenosine triphosphate (ATP). Muscles use ATP as a source of energy to contract and carry out their functions. The process by which ATP is produced and utilized in muscles is called cellular respiration.
During rapid exercise how do your muscles produce ATP?
Fueled by the metabolism of sugar, the ATP byproducts (ADP) are reconstituted into ATP molecules. Use of ATP energy requires no oxygen - when the ATP is depleted the muscle cells must use cellular respiration to obtain energy and once the muscle is at rest the ATP stores are replenished.
What are metabolic energy that do not require oxygen?
Anaerobic metabolic pathways, such as glycolysis, do not require oxygen to produce energy in the form of adenosine triphosphate (ATP). These pathways break down glucose and other molecules to generate ATP quickly without relying on oxygen as the final electron acceptor. However, they are less efficient than aerobic pathways in terms of energy production per molecule of glucose.
