CHEM120 Week 7 Concepts: Biochemistry – Download For Revision And Improve Your Grades LIPIDS In this concept, we will discuss one class of biological polymers called lipids or fats. You might be f amiliar with this class of biopolymers, which are found in butters and oils. We will discuss saturated and unsaturated fats, and what those terms mean for the molecule's structure as well as its properties at room temperature. 1. Which of the following is a source of lipids? • Sugar, fruits, and b...

Summary of the biochemistry notes best solutions Basic principles govern energy maniulations in cells - 1) Molecules are degrades or synthesized stepwise in a sries of reactions termed metabolic pathway. 2) ATP is the energy currency of life 3) ATP can be formed by the oxidation of carbon fuels 4) Metabolic pathways are highly regulate Oxidation - loss of electrons, Reducing agent(reductant)-donanates ectrons, oxidized. For every biological oxidation there is a corresponding reduction. ...

MSCI 530 Quiz – Lipid Metabolism (Questions and Answers)

BISC 312 Exam 2 Terms in this set (163) Regulation of enzyme activity by covalent modification covalent modifications are often reversible and are done by enzymes which are themselves subjected to regulation. Extremely common strategy (ex. phosphorylation or dephosphorylation) phosphorylation by kinases and dephosphorylation by phosphatases utilize an ATP that adds a phosphate group to a specific amino acid on an enzyme zymogems proenzymes or inactive forms of enzymes regulati...
