The list which correctly summarizes the main functions of proteins in the human body is the last one - p<span>owering movement, structural support, hormone production, antibody and enzyme production.
Skeletal muscles are responsible for movement and those muscles are made of protein. </span>
Answer:
(look at explanation)
Explanation:
Cardiac muscle tissue works to keep your heart pumping through involuntary movements. This is one feature that differentiates it from skeletal muscle tissue, which you can control. It does this through specialized cells called pacemaker cells. These control the contractions of your heart.
I don't think one process can go on continuously without the other. Because during the photosynthesis carbon dioxide is necessary along with sunlight, water to make glucose and oxygen. Without oxygen we won't survive if we don't survive then there will be no carbon dioxide. Aerobic respiration is when you take in oxygen made by plants in the process of photosynthesis as the product of aerobic respiration we breath out carbon dioxide which plants use to make glucose and oxygen.
The living cell main source of energy is the sun.
Answer:
All antigen receptors produced by a single B or T cell are identical and bind to the same epitope.
Explanation:
Epitope or antigen determinant is the specific part of the antigen that is recognized by an antibody or T-cell receptor. During clonal selection, a lymphocyte proliferates and differentiates to form a group of highly specialized cells in response to a specific antigen present in the body.
The result of clonal selection is the formation of a population of identical cells that recognize the same specific epitope of the same antigen. A lymphocyte that undergoes clonal selection gives rise to two major types of cells in the clone: effector cells and memory cells.
For instance, the clonal propagation of B lymphocytes forms plasma cells (the effector cell) and memory cells. The plasma cells synthesize and secrete specific proteins called antibodies. All the antibodies derived from a plasma cell can bind to and inactivate the same specific antigen.
