Answer:
Explanation:
a.
Actin and myosin, two contractile proteins, make up myofibrils. ATPase activity is present in the myosin head. Troponin tropomyosin complex is displaced by calcium ions, exposing myosin's entire surrounding binding site on actin. Myosin heads execute the power stroke, and detachment of the head is needed for the second cycle. Myosin head detachment is aided by ATP binding & hydrolysis. Since the solution contains AMP-PNP instead of ATP, myosin heads are unable to hydrolyze and detach from myosin-binding sites on actin, thereby preventing contraction.
b.
The active ATPase correlated with both the dynein arms is found in cilia and flagella. Dynein is a motion motor protein family that walks around microtubules. The core of cilia is made up of microtubule bundles linked to the motor protein dynein. In the presence of AMP-PNP, the net reaction will be to stop the ciliary movement by inhibiting dynein motor proteins.
c.
Kinesins and Dyneins, two groups of motion motor proteins with ATPase activity, are involved in axonal transportation. All the motion motor proteins use energy from ATP hydrolysis to transfer secretory vesicles through microtubules. Since the inclusion of AMP-PNP does not supply electricity, vesicular transport does not occur.
Answer:
A plant cell...
Explanation:
Animal Cell Has no cell wall, and its only plant cell and eukaryotic cell that has all those things
Answer: It is A near the back just above the occipital
Explanation:
Answer:
Explanation:
During the lytic cycle, bacteria takes over the cell, reproduces new phages, and destroys the cell. It works in 5 phases
1. The virus or phage attaches itself to the cell
2. The phage enters the cell
3. Biosynthesis- Phage DNA replicates and makes phage proteins
4. New phage cells assemble
5. The cell lyses emerge with a new plague
Answer:
Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air.
