Answer:
Cell surface receptors (membrane receptors, transmembrane receptors) are receptors that are embedded in the plasma membrane of cells. They act in cell signaling by receiving (binding to) extracellular molecules. They are specialized integral membrane proteins that allow communication between the cell and the extracellular space.
Explanation:
Answer:
if your brain is distracted, then you'll have a slower reaction time. if not, then you have a faster reaction time.
Other things can depend. If the object is to fast or to slow, that could also delay reaction times.
Explanation:
Preparing for Cellular Respiration.Cells,including bacteria, can be though of as energy producing factories that take nutrients and convert them into energy called adenosine triphosphate(ATP) Glycolysis is the first step in breaking down glucose to Obtain energy through cellular respiration in bacteria.

"The heart rate increases during the exercise because the "adrenaline rush" signals for the heart to beat faster and to increase the oxygen delivery to muscles."
The heart normally beats more quickly during physical activity so that more blood can reach the body. By pumping more vigorously or by increasing the volume of blood that fills the left ventricle before it pumps, the heart increases the stroke volume. The amount of oxygen the muscles need to make energy increases during exercise. The heart needs to pump more oxygen-rich blood through the arteries during the exercise to meet the energy requirement.
