The answer should be both
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:
prophase
Explanation:
Prophase is when the nuclear membrane degrades. Metaphase is when the chromosomes align in the middle of the cell. Anaphase is when the chromosomes are pulled apart. Lastly, telophase is when one cell splits into two separate cells.
Answer:
1. When you eat, you take in large molecules called "macromolecules" which make up building blocks that you can absorb into the bloodstream, and that your cells burn for energy.
2. Sugar molecules - Glucose, Amino Acids - Proteins, Fatty Acids - Fat
3 - 5 seems like answers you have to do yourself, but if you really need help just comment and I'll edit this!
Explanation:
The cell grows, makes a copy of its DNA, and prepares to divide into 2 cells.
Or for APEX---->The chromosomes are duplicated or the cells prepare for mitosis
The cell prepares for mitosis.
Organelles are manufactured(apex)
