Not for long. We use oxygen for cellular respiration and plants make oxygen so if all the plants died, we would only have so long to live
Answer:A. The release of calcium ions causes myosin and actin to attach to each other.
The contraction of skeletal muscles takes place by induction of a nerve impulse, which produces a movement and the interaction of the filaments containing proteins named as actin and myosin. This interaction of filaments is regulated by proteins called tropomyosin and troponin present on the actin filaments. The motor nerve causes the depolarization of the muscle membrane sarcolemma. This triggers the sarcoplasmic reticulum to release calcium ions. This calcium binds to troponin and thus allows the tropomyosine strand on the actin filament to displace so that the part of the actin where myosine head needs to be attached remain uncovered. Binding of the actin myosine filament results in contraction.
Hence, the release of calcium ions causes myosin and actin to attach to each other causes muscle contraction.
Answer:
d
Explanation:
ATP stands for Adenosine Tri Phosphate, and that third phosphate is bonded to the other two with a very high energy bond, so a lot of energy is released when that bond is broken. When the third phosphate is removed from ATP, you get ADP, which stands for Adenosine Di Phosphate.
