Which protein inhibits interaction between actin and myosin to prevent skeletal muscle contraction; and which ions remove the in

Biology
1 answer:
zloy xaker [14]3 years ago
7 0

Answer:

Tropomysin, calcium

Explanation:

Tropomysin is a protein that prevents muscle contraction hence acts as a contraction inhibitor. It wraps around the actin blocking the binding sites for myosin on the actin.

Muscle will only contract when they get a rush of calcium ions.

The calcium ions binds to troponin, the troponin changes its shape. The change in shape will remove tropomyosin from the binding sites allowing myosin to bind on the actin leading to muscle contraction.

Define the components of blood and briefly describe their role.
Grace [21]
Tha main components in blood are the plasma, red blood cells, white blood cells, and blood platelets.

Plasma is like the main component that makes up most of the blood. It has a light yellow color and it carries many substances including nutrients, waste, hormones and more.

Red blood cells are the reason why blood is red in color. They have a hemoglobin inside them which can help carry oxygen for the tissues and organs. In order to maximize the oxygen carrying capacity, they don't have a nucleus.

White blood cells can be divided into phagocytes and lymphocytes. Their main function is to protect us from diseases. Phahocytes and engulf and digest bacteria, while lymphocytes can produce antibodies.

Blood platelets can cause blood clotting which can stop us from bleeding forever. They're not cells, but just fragments of cells. They also don't have nucleus since they're not complete cells.

Yakvenalex [24]

Answer:

Fibrous  is the type of joint involved.

Explanation:

Diarthrosis is present at articulating bones which is responsible for the movement. Surrounding synovial capsules identifies it. synovial capsules which secretes synovial fluids to nourish and lubricate the joints while it acts as a shock absorber, surrounds the bones of synovial joints.

Smooth, hyaline cartilages which is of glass like, reduces the friction while movement and are present at the lower of the joint bones. this synovial cavity and regular, dense connective tissue which is responsible for the formation of articular capsules related with accessory ligaments.
