3 mechanisms of microevolution - natural selection, genetic drift, gene flow 3 modifications made during RNA processing - - adenines added to poly-A tail - 5' end recieves a guanine cap - RNA splicing 3 steps of DNA replication - initiation, elongation, termination active transport - movement of molecules across a plasma membrane against from low concentration to high concentration with the expenditure of energy (ATP) by the cell adhesion - An attraction between molecules of different su...

MCAT General Chemistry | Latest Update | 2024/2025 | Already Passed What is the role of the conjugate base in an acid-base reaction, and how does it influence the reaction equilibrium? The conjugate base is formed when an acid donates a proton. It influences the reaction equilibrium by interacting with the acid, shifting the equilibrium based on the relative strengths of the acid and its conjugate base. How does the presence of a common ion affect the solubility of a salt in a solu...

Metabolism - all chemical reactions that occur within a cell Anabolic Pathways - pathways that produse cellular components, increase in molecular order, decrease in local entropy, endergonic, synthesize polymers in order to store energy Catabolic Pathways - pathways that breakdown cellular components, decrease in molecular order, increase in local entropy, exergonic, produce small molecule building blocks to release free energy Bonds in ATP - phosphoanhydride bonds between third and sec...

What are the four rules for writing resonance structures? - Answer 1. Atoms must not be moved. Only electrons. 2. All resonance atoms must lie in the same plane. 3. Only valid Lewis structures are allowed. 4 . The number of unpaired electrons must remain constant. What are the two conditions for resonance? - Answer 1. An atom must have a P orbital or a lone pair of electrons. 2. It must be single bonded to an atom that has a double or triple bond. The latter compromise conj...

BIO 441A EXAM 3 STUDY GUIDE WITH COMPLETE SOLUTION. LECTURE ONE - METABOLISM INTRODUCTION ● Autotrophs synthesize all their own cellular constituents from simple molecules ● Heterotrophs obtain energy through oxidation of organic compounds and therefore rely on autotrophs ● Metabolism involves many reactions such as ○ Glycolysis/gluconeogenesis ○ The citric acid cycle ○ Oxidative phosphorylation ● Catabolism is the degradation of biomolecules ○ Energy rich nutrients are...
