Answer:
They slowly lose energy.
Explanation:
High-energy electrons give the chain either NADH or FADH2 to complete it.
Low-energy electrons form water by decreasing the oxygen molecules.
<span>Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back intocarbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, incellular respiration oxygen is combined with hydrogen to form water.</span>
Answer:
d. ATP is present and the intracellular Ca2+Ca2+ concentration is high.
Explanation:
Myosins are motor proteins that plays a major role in muscle contraction. They depend on ATP and responsible for motility in actin-based substances. Skeletal muscle is composed of myosin and actin fibers. Each myosin thick filament is surrounded by actin thin filaments, and each thin filament is surrounded by thick filaments. There exists a strong attraction between the myosin head and the myosin-binding site of actin which binds them spontaneously. This bond is aided by the presence of ATP and the high concentration of intracellular Ca2+. The myosin protein undergoes a change in its shape.
