Answer:
1. myosin ATPase
2. Ca2+-ATPase
Explanation:
ATPase activity of myosin head hydrolysis ATP and energize the myosin head. The energized myosin head forms cross bridges to facilitate the power stroke of muscle contraction. The fast-twitch oxidative-glycolytic fibers have the ability to produce ATP by aerobic respiration.
These fibers have the ATPase in their myosin heads that hydrolyze ATP three to five times faster than the myosin ATPase in slow fibers. This ensures the faster speed of contraction of these fast-twitch muscle fibers.
During their relaxation, Ca2+ ATPase pumps the calcium ions back to the sarcoplasmic reticulum. As the level of Ca2+ ions in the sarcoplasm decreases, calcium ions are released from troponin. Tropomyosin is allowed to cover the myosin-binding sites on actin and the muscle fiber relaxes faster.

An organism that contains foreign DNA, which was inserted into its own genetic material, is called transgenic.
Answer:
Following are the organelles present in the cell.
nucleus
mitochondria
ribosomes
lysosomes
endoplasmic reticulum
vacuole
Golgi bodies
Explanation:
Nucleus is the central part of the cell which control all activities in the cell. Mitochondria is also called power house of the cell which is responsible for the production of energy for the cell. Ribosomes and endoplasmic reticulum are responsible for the production of proteins. Lysosomes collects and removes the waste material from the cell. Vacuole store nutrients and food materials for the cell while golgi bodies modifies the protein.
