Answer:
b
Explanation:
its b. pseudoscience says that its science, but they don't really,,, do science
Proteins. they are a string of amino acids
<h2>Capillary Smooth Muscle Contraction</h2>
Explanation:
- Blood flows through blood vessels, which form the closed system called the circulatory system. Like a system of roads, the circulatory system has its highways, back roads, and alleyways, which we call arteries, veins, and capillaries
- Capillaries are the alleyways that extend and branch into every tissue of your body, ensuring that every cell has a blood supply. It is here, in the capillary beds, that your cells pick up oxygen and nutrients and drop off carbon dioxide and wastes
- Muscles are composed of two major protein filaments: a thick filament composed of the protein myosin and a thin filament composed of the protein actin. Muscle contraction occurs when these filaments slide over one another in a series of repetitive events
- All muscles contract as a result of interaction between special proteins within the myocytes. Skeletal, cardiac, and smooth muscle cells synthesize the contractile proteins actin and myosin, which are needed for muscular contraction
Curare will bind to the receptor but it doesn't cause the ion to flow inside. This will prevent the person from sent signal to the muscle. When the person trying to move the muscle, curare will also prevent acetylcholine to bind so there will be no muscle contractions. The symptoms would be paralyzed of muscle that uses ach receptor.
Answer:
<em>Some enzymes help break large molecules into smaller pieces that are more easily absorbed by the body. Other enzymes help bind two molecules together to produce a new molecule. Enzymes are highly selective catalysts, meaning that each enzyme only speeds up a specific reaction.</em>
