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.
Answer:
Explanation:
-Sodium-potassium pump (exchange of sodium and potassium ions across cell walls)
-Amino acids moving along the human intestinal tract.
-Calcium ions moving from cardiac muscle cells.
-Glucose moving in or out of a cell.
-A macrophage ingesting a bacterial cell.
Answer:
Space Research
Explanation:
There are numerous experiments going on at all times on the International Space Station, the majority of which cannot be done on the Earth. This research can potentially provide the information needed to help humans travel to other planets, clues about the formation of the universe, and even have applications in medicine.
Surgical cutting of the lingual frenulum would occur in the part of the body which is known as a) tongue.
Lingua literally means tongue, or language.
Answer:
<em>Vacuole</em>
Explanation:
Vacules are the storage bubbles within the cell. They store food, nutrients and/or other organic compound which might cell require during starving conditions. They are more than one in animla cells but relatively smaller. The diagram shown is the schematic representation of the animal cell.
