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...

If the G'° of the reaction A -> B is -40 kJ/mol, under standard conditions the reaction: A) is at equilibrium. B) will never reach equilibrium. C) will not occur spontaneously. D) will proceed at a rapid rate. E) will proceed spontaneously from left to right. Answer- E) will proceed spontaneously from left to right. For the reaction A - B,G'° = -60 kJ/mol. The reaction is started with 10 mmol of A; no B is initially present. After 24 hours, analysis reveals the presence of...

BIOL 2400 Final Exam Questions With Answers Latest 2023/2024 (Graded 100%). SNP data (the third codon position of a nuclear gene) from 1000 individuals on the enzyme Phosphoglucose isomerase (PGI) was collected from two populations of perch in two local rivers and also from Guelph Lake. As is usual for a SNP only two alleles were found: A1=C and A2=G. The genotype data for each population is given in the Table 1 below: Table 1: Perch genotypes: CC CG GG p(C) q(G) Eramosa R. .4 0.6 Spee...
