Answer:
Corticosteroid drugs
Explanation:
Corticosteroid drugs are most similar to the hormones that the adrenal gland produces.
Answer:
Skin immunity is a property of skin that allows it to resist infections from pathogens. In addition to providing a passive physical barrier against infection.
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 digestion of carbohydrates begins in the mouth and ends in the small intestine.
Explanation:
The absorption of carbohydrates, depending on whether they are simple or complex, will begin their digestion in the mouth by the action of saliva in food, where starches are initially separated; Once this food bolus reaches the stomach, the hydrochloric acid acts, to end later in the small intestine. Amylase, a component of pancreatic juice, ends the digestive process of carbohydrates by transforming starches into maltose, which are then transformed into monisacarides (glucose, galactose, fructose), which is the way they are absorbed by the body. In the liver they are again transformed into glucose.
