Answer: The correct option is D.
The concentration of calcium in the myofibril must decrease.
Explanation:
This is because calcium makes myosin, actin and ATP to interact which actually lead to the contraction of muscle fibre.
Relaxation of muscle fibres occurs when the nerves stop stimulating. The result in the pumping of Calcium into the sarcoplasmic reticulum which then cause a break in the link that connect actin and myosin. Actin and myosin return to their unbound state leading to the relaxation of the muscle .
Answer:
Both are hydrophobic
Explanation:
Because first of all Internal start- transfer process is a process where a peptide is transfered to the side opening of translocon and then then fixes itself in the membrane, whereas
Stop-transfer sequences in proteins act to stop this process of translocation and moves out through the side opening in translocation to fix itself on a membrane this is consistent with the hydrophobic nature that repels water. Because they are non polar and lack the capacity to form a hydrogen bond with another molecule
I'm pretty sure its c or d
A cell would have 46 chromosomes during metaphase I.
