Answer:
The correct answer will be:
1. Acetylcholine binds to receptors on the motor end plate
2. Chemically-regulated ion channels open, causing depolarization
3 End plate potentials trigger action potential(s).
4. Transverse tubules convey potentials into the interior of the cell
5. Ca++ is released from the sarcoplasmic reticulum
6. Ca++ binds to troponin, pulling on tropomyosin
7. Binding sites on actin are uncovered, allowing myosin to bind and carry out power strokes
8. Force increases.
9. Ca++ is pumped (re-sequestered) into the sarcoplasmic reticulum
10. Force decreases.
Explanation:
The muscle contraction is a highly controlled mechanism which begins at the neuromuscular junction with the release of the acetylcholine neurotransmitter. This neurotransmitter causes the depolarization of the membrane by binding to the receptors of the motor end plate which generates an action potential. This action potential is transmitted via T-tubules from sarcolemma to the sarcoplasmic reticulum.
The sarcoplasmic reticulum releases calcium ions which binds to the troponin protein. This troponin removes the protein tropomyosin from the actin causing the rotation of the tropomyosin exposing the binding sites for myosin. The myosin binds to the actin using energy from the ATP which pulls the actin causing contraction. Another ATP binds the myosin head which weakens the bond between myosin and actin which releases the myosin which decreases the force between them decreases and the muscles relax.
Answer:
The correct word to be fill in the blank is 'energy.'
Explanation:
Secondary active transport is a type of active transport, which involves transport of molecules or ions across the membrane against their concentration gradient by using energy.
In secondary active transport, energy is provided by electrochemical gradient. It involves transport of two molecules or ions (either in same or opposite direction) and required energy is generated due to difference in electrochemical gradient formed by pumping or ions across the cells.
An example of secondary transport is transport of potassium ions by K+/H+ exchanger that transports hydrogen ions and potassium ions in opposite direction. It uses energy from proton motive force (generated by transport of hydrogen ions or protons) to transport potassium ions.
Thus, the correct answer is 'energy.'
Answer:
renal column
Explanation:
The renal column is also known as Berlin column . It is a medullary expansion of the renal cortex in the middle of the renal pyramids. It enables the cortex to be better tied down. Every section comprises of lines of veins and urinary cylinders and a sinewy material.each renal columns comprises of lines of veins and urinary cylinders and a sinewy material.
Answer:Aged cheeses
Explanation:Aged cheeses are rich in tyramine, which interacts with MAO inhibitors to raise blood pressure to life-threatening levels. Patients taking MAO inhibitors should be taught to avoid tyramine-rich foods. Chianti wine contains tyramine, but other alcoholic beverages do not. Brussels sprouts and cabbage are foods rich in vitamin K, which can interfere with the effects of warfarin. Grapefruit juice inhibits CYP3A4 and interferes with the metabolism of many medications.
