Answer:
When the muscle starts to contract and needs energy, creatine phosphate transfers its phosphate back to ADP to form ATP and creatine. This reaction is catalyzed by the enzyme creatine kinase and occurs very quickly; thus, creatine phosphate-derived ATP powers the first few seconds of muscle contraction.
A phenotype is the physical appearance of a characteristic.
A genotype is the code for that characteristic.
<span>Diffusion and osmosis are important to cells because they don't require energy to transport very important molecules such as water and steroids.</span>
I think the answer is evolution.
