Atp plays a critical role in muscle. Breaking of the cross-bridge is possible only if atp binds to myosin, thereby allowing it to be free for the following contraction.

What is the role of ATP in maintaining calcium concentration gradients?
Calcium must be actively pumped back into the terminal cisterns of the sarcoplasmic reticulum to terminate the contraction and relax the skeletal muscle. For every Ca2+ transported, one ATP molecule is hydrolyzed.
An increase in the concentration of ATP in a muscle cell is a direct result of which life function?
Cellular Respiration
Does muscle relaxation does not require ATP?
Both muscle relaxation and muscle contraction require ATP.
What is the role of myosin APT ase in muscle contraction?
Myosin ATPase hydrolyze ATP into ADP+pi and yielding the energy required for muscle contraction.
What type of muscle is rich in ATP?
Muscle fibers are rich in ATP. All muscle fiber types are rich in ATP (having many mitochondria).
What is the relationship between the relative concentrations of molecule X and the use of ATP for diffusion?
High concentration to low concentration. ATP not used
What role does active transport play in diffusion?
active transport is kind of like diffusion, but unlike diffusion, it requires ATP(energy) and the molecule moves from low concentration to high concentration
Why is atp important in muscles?
ATP is important in muscle contraction. ATP is high energy bond which gives you energy required for muscle contraction.
Why di muscle cells have many mitochondria?
Muscle requires a lot of ATP , mitochondria produces ATP
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.
Percentage of contraction observed with solution containing ATP?
The percentage of contraction observed with a solution containing ATP will vary depending on the tissue or muscle being studied, as well as the concentration of ATP and other factors like temperature and pH. In general, ATP can induce muscle contraction by providing energy for the cross-bridge cycling between actin and myosin filaments. Experimental conditions must be carefully controlled to accurately measure the extent of contraction induced by ATP.
What is the natural tendency of molecules to spread from an area high concentration to an area of low concentration?
Diffusion is the movement of molecules from a high concentration to a low concentration without using ATP (energy). A related term: Osmosis is the movement of water molecules from a high concentration to a low concentration without using ATP (energy). In contrast, active transport is the movement of molecules from a low concentration to a high concentration but DOES use ATP (energy).
