It requires energy when a substance must travel against a concentration gradient through the membrane
For the first question, I believe it's 36. For the second question, it is oxygen, as oxygen is essential for aerobic processes. For the last question, the summarized cellular respiration equation is the 2nd one.
<span>ATP is used in the formation
of the polypeptide in the ribosome during translation. It induces the transport
of amino acid by tRNA. ATP is a pressure for the synthesis of RNA and DNA. As an
Adenosine Triphosphate, it is one of the 4 monomers nucleosides, when transformed
to dATP, that are used to synthesize DNA</span>.
ATP is also used to transport materials across
the cell membrane against a concentration gradient.
The ears i think so it can hear predators
DNA helicase is the enzyme that unwinds the DNA double helix by breaking the hydrogen bonds down the center of the strand. It begins at a site called the origin of replication, and it creates a replication fork by separating the two sides of the parental DNA.
Hope this helps!
