Bis 2a - Study guides, Class notes & Summaries

Britt Bis 2A Midterm 2 study guide DUE 9 OCTOBER 2023 1. A protein's tertiary structure is stabilized by... a. Hydrophobic R groups b. Ionic bonds c. Phosphodiester bonds d. Hydrogen bonds e. a, b, and d -CORRECT ANSWER- e. a, b, and d In animals, if the fuel consumed exceeds energy expended, fats are synthesized from carbohydrates in order to store the excess energy. Acetyl-coA Carboxylase catalyzes the first dedicated step in fatty acid synthesis. This enzyme responds to a larg...

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...

BIS 2A What is the difference between channel proteins and carrier proteins? - CORRECT ANSWER-While they are both transport protiens active in facilitated diffusion, channel protiens are always open and work faster than carriers. While carrier protiens bind to a substance and change shape for that substance to pass through. What is Tonicity? - CORRECT ANSWER-The ability of an extra cellular solution to change in volume by affecting osmosis. What is osmoregulation? - CORRECT ANSWER-Mec...

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 2023 What are proteins made of? - CORRECT ANSWER-Proteins are made up of amino acids linked together by peptide bonds, as well as the R groups attached to the amino acids (which make them unique and give certain characteristics) Proteins are formed through the process of condensation, when the carboxylic group and the amine group of the amino acids bind together to produce water, forming a peptide bond. How the various levels of organization (primary, secondary...) affect the s...
