Document Summary
Gtp another energy source, derivative of nucleotide: holds slightly less energy. Not worried about living systems running out of free energy because of the sun. Atp has a range of energy: lower value calculated in lab, higher value what the cell can actually do in the body. Induced fit: enzyme has certain shape, substrate binding changes the enzymes shape so the substrate fits better. Systems biology: way of looking at different biological processes in totality rather than looking at each pathway individual properties, emergent properties sum is greater than the whole. Important in cancer compare healthy cells to cancerous cells. Nerve gas irreversible inhibition: covalently binds into active site of acetylcholinesterase never leaves the enzyme, leaving it inactive, acetylcholine binds to receptors on other neurons to communicate signals. Important in converting acetylcholine (neurotransmitter) acetate and choline. Acetylcholine is not broken down and the signal gets sent over and over and over again.
