Describe the events of muscle cell contraction?
6 steps in a muscle contraction
Starting with the release of acetylcholine what are the steps in muscle contraction?
Acetylcholine released by the motor neuron at the neuromuscular junction changes the permeability of the cell membrane at the motor end plate. The permeability change allows the influx of positive charge, which triggers an action potential. The action potential spreads across the entire surface of the muscle fiber and into the interior via T tubules. The cytoplasmic concentration of calcium ions (released from the sarcoplasmic reticulum) increases, triggering the start of a contraction. The contraction ends when AChE removes the ACh from the synaptic cleft and motor end plat
Describe the Normal sequence of events which lead to muscle contraction?
Action potential, release of calcium, change in tropomyosin conformation, attachment of globular myosin heads, release of ATP energy, movement of the Z-lines.
1 Describe the ionic events underlying the nerve action potential 2. Describe the steps in cross bridge cycle that produces skeletal muscle contraction.?
thick filaments pulling thin filaments toward the center of the sarcomere
Why is it if a person steps on a nail you move your foot fact which nervous system tell you to respond to the contraction?
If a person steps on a nail and moves his or her foot fast, it is an example of a reflex from the peripheral nervous system that registers pain from the contraction. More accurately, it is a crossed-extensor reflex.
What is used to support steps of a geometric proof?
Steps in a geometric proof do not require support
What are the 10 steps to follow when attempting to answer questions related to number theory?
There is no standard set of ten steps: some questions require far fewer, other require more.
How many steps do you have to take to evolve a drowzee egg?
The hatching of Drowzee Pokémon Eggs will require approximately 5,120 steps.
What is 1 748 divided by 23 with the steps?
1 748 divided by 23 results in 76 (seventy six). The steps require a calculator
What steps are involved in the process of making tiles out of crushed shells?
The steps involved are: * pass the crushed shells through a kiln. This gives lime (calcium hydroxide), from the calcium carbonate which forms the shells. *now, add the lime to fine sand and press the mixture into tile shape *finally, pass the tiles through the kiln again under high pressure This results in calcium silicate tiles
What steps require energy?
To get JUST ABOUT ANYTHING done requires at least some energy.
Which steps in aerobic cellular respiration require oxygen?
electron transport chain
