Answer:
to maintain homeostasis
Explanation:
The bionic pancreas is a technology created to reduce and adjust blood sugar levels in patients with diabetes. This external device was developed by Ed Damiano's lab at Boston University. This management system is well known to maintain homeostasis by managing blood sugar levels: the bionic pancreas contains two pumps, one with insulin and the second one with glucagon for controlling the sugar levels when they change in the blood.
Answer:
D. Molecules called pumps function to control active transport.
Explanation:
Active transport is one of the two types of transport (the other being passive transport). It is the type of transport in which substances move against their concentration gradient i.e. from a lower concentration to a higher concentration. Hence, due to this, energy input in form of ATP is required by the cell.
However, the process of active transport makes use of certain molecules called PUMPS to control it. The pumps moves ions/molecules against their concentration gradient. An example is the sodium-pottasium pump which moves sodium ions from a region of low conc. to a region of high conc.
Answer:
sympathetic stimulation
Explanation:
Under stress or emergency conditions, the preganglionic neurons of the sympathetic division release acetylcholine. Acetylcholine stimulates secretion and release of epinephrine and norepinephrine from the adrenal medulla. These hormones enhance the effects of the sympathetic division of the autonomic nervous system (ANS) during stress. Epinephrine and norepinephrine augment the fight-or-flight response as they increase the heart rate and force of contraction, the output of the heart, and blood pressure. They also increase blood supply to the heart, liver, and adipose tissue. The airways to lungs become dilated and there are increase blood levels of glucose and fatty acids.
The Krebs Cycle is involved in cell respiration and produces NADH and FADH2 for the electron transport chain. So your answer would be "<u>Release energy for making ADP</u>".
