threshold stimulus
ATP is needed for muscle contraction because it provides the energy necessary for the muscle fibers to contract and generate force. Without ATP, the muscle fibers would not be able to function properly and contract effectively.
When ATP attaches to a myosin head during muscle contraction, it provides the energy needed for the myosin head to detach from actin, allowing the muscle to relax and reset for the next contraction.
An action potential. It is the nerve impulse that enters into sarcomeres from the sarcoplasmic reticulum and provides the energy for the calcium ions to briefly bind to the troponin on the actin myofilament to allow for contraction to occur by bringing the Z-lines closer together.
ATP (adenosine triphosphate) is the energy source that powers muscle contraction. When a muscle needs to contract, ATP is broken down into ADP (adenosine diphosphate) and inorganic phosphate, releasing energy that is used to fuel the contraction process. This energy allows the muscle fibers to slide past each other, generating the force needed for movement. In essence, ATP is essential for providing the energy needed for muscle contraction to occur.
Calcium is essential for muscle contraction because it binds to a protein called troponin, which triggers a series of reactions that allow the actin and myosin filaments in muscle cells to interact and produce force. Without sufficient calcium, the muscle cells cannot contract effectively.
Threshold Stimulation
true
It is the variation of stimulation needed in skeletal muscle contraction in order to have controlled movement.
A muscle fiber will not respond to a stimulus until that stimulus reaches the threshold level needed to trigger an action potential. This threshold level is the minimum amount of stimulus required to elicit a response from the muscle fiber.
Threshold
The minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called?
Perceptual threshold refers to the minimum level of stimulus needed for a person to detect a particular stimulus. It is the point at which the stimulus becomes strong enough to be recognized by an individual's senses.
the standard of living
The point at which a person can detect a stimulus 50% of the time it is presented is known as the absolute threshold. This threshold represents the minimum intensity of a stimulus needed to detect it half of the time. It is often used in psychology to study perception and sensory processing.
The minimum level of stimulation required to trigger a neural impulse is known as the "threshold." This threshold is the minimum amount of neurotransmitter release or electrical stimulation needed to generate an action potential in a neuron. Below this threshold, the neuron will not fire an action potential.
yeah
The minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called critical mass.
