Smooth muscle fibers can sustain a contraction without fatigue by allowing dephosphorylated myosin to remain attached to actin in what is called the <u>Latch State</u>.
Latch State- Myosin cross-bridge creation with actin is prevented by dephosphorylating its RLCs, however dephosphorylating myosin that is already attached to actin slows down its off rate, creating the so-called "latch state." In the latch state, smooth muscle maintains tension while undergoing modest rates of ATP hydrolysis.
ATP hydrolysis- When the high-energy phosphoanhydride bonds in adenosine triphosphate are split, as occurs, for example, in muscles, chemical energy that has been stored in them is released. This process is known as ATP hydrolysis.

Answer:
Photosystem II (PS II) only : oxidation of water, reduction of electron transport chain between the two photosystems
Photosystem I (PS I) only: reduction of NADP+ , oxidation of electron transport chain between the two photosystems
both PS II and PS I: light absorption, reduction of primary electron acceptor
Explanation:
The answer is D. The hotter something is, the more kinetic energy it has.
