BIOL 1000 Study Guide - Midterm Guide: Non-Competitive Inhibition, Competitive Inhibition, Signal Processing
Document Summary
The bigger the cell, the more waste the more generated and the more nutrients required. More waste and nutrients must be transported in and out of the cell and this process is difficult to accomplish in larger cells due to the lower surface area in relation to volume. Smaller cells have more surface area for oxygen and nutrients to transport in and carbon dioxide to transport out. Gram-positive bacterial cell walls are largely made of peptidoglycan, which is not found in eukaryotic cells. Competitive inhibitor molecules can directly compete with a substrate to bind an enzyme"s active site while a non-competitive inhibitor molecule binds to the enzymes at the location other than the active site called the allosteric site. Both competitive inhibitor and non-competitive inhibitor serve the same purpose but when a competitive inhibitor binds to the active site, a high concentration of substrate should outcompete the competitive inhibitor for the enzyme"s active site.
