Answer:
D) the thylakoid and mitochondrial inner membranes.
Explanation:
Electron transport chain in plant cells is used for extracting sunlight energy via redox reactions through the process of photosynthesis. This process occurs in chloroplast (thylakoid membrane), where light energy is transformed into chemical energy, that leads to the conversion of water to oxygen and NADP+ to NADPH with transfer of H+ ions across chloroplast membranes. Formed H+ gradient is used for the ATP synthesis.
In all eukaryotes, including plants, electron transport chain is located in the inner mitochondrial membrane where it serves as the site of oxidative phosphorylation (production of ATP) through the action of ATP synthase.
In a sperm cell and for females it’s the egg cell
Answer and explanation:
Antibodies are structures made of four polypeptides, <em><u>two light (L) chains and two heavy (H) chains that join together and form a molecule shaped like a "Y"</u></em>. This structure is possible thanks to the <u>disulfide bonds</u> that bind light chains and heavy chains together. While the stem of the Y is constant and doesn't change ("<em>constant region</em>"), the tips of the Y, composed of 110-130 amino acids and called "<em>the variable region</em>", vary greatly among the different antibodies and are responsible for the high specificity of these molecules.
<u>This is why we could say that the primary structure of this protein is given by disulfide bridges that twist the antibody and allow it to bind to a protein from the flu virus.</u>
Answer:
earth's trash ring
Explanation:
earth has a ring of trash around its self of space junk that never made it to the destination it was ser for along with failed pieces that could handle the pressure of space travel.
Answer:
C. release energy
Explanation:
Cardiovascular fitness refers to the ability of the heart and lungs to supply oxygen-rich blood to the working muscle tissues also the ability of the muscles to use oxygen to produce energy for movement.
Aerobic excercises lead to the breakdown of glycogen to glucose.
Oxygen is used to burn fats and glucose will be used to produce ATP (Adenosinetriphosphate) the basic carrier of energy
Cardiovascular exercises include walking, jogging, running among others.
