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...
