BIS 2A MIDTERM 2 2023/2024 On early Earth, the first things that looked like they might be classified as living organisms used iron sulfur clusters as catalysts. If these "naked" iron sulfur clusters can catalyze reactions, why do our cells instead use proteins carrying iron sulfur clusters as catalysts? a. To decrease substrate specificity b. To increase substrate specificity c. To prevent spontaneous oxidation of the iron in the cluster d. a and c e. b and c - CORRECT ANSWER-e. ...

BIS 2A Midterm 1 Britt Which of the following statements best describes covalent bonds? - CORRECT ANSWER-the sharing of an electron pair between atoms; relatively strong bond Which of the carbon atoms is most oxidized? - CORRECT ANSWER-CO2 How can living things grow and display increasing levels of order, reorganizing random molecules into complex organized molecules? - CORRECT ANSWER-living things capture the energy from their environment, like nearby exergonic reactions, and use tha...

What is the difference between channel proteins and carrier proteins? - ️️While they are both transport proteins active in facilitated diffusion, channel proteins are always open and work faster than carriers. While carrier proteins bind to a substance and change shape for that substance to pass through. What is Tonicity? - ️️The ability of an extra cellular solution to change in volume by affecting osmosis. What is osmoregulation? - ️️Mechanism of controlling the affects of os...
