Biology 1201 LSU Exam 2 Questions and Answers 100% Pass What type of chemical reaction is without outside energy? Spontaneous (exergonic/downhill) NOT INSTANTANEOUS -decreasing enthalpy and increasing entropy What is the equation for Free Energy? deltaG=deltaH-TdeltaS -free enrgy=enthalpy-(temp.)(entropy;disorder) -high deltaS=low delta G Entropy Disorder: -breakdown: increase in disorder, more parts -synthesis: decrease in disorder, less parts -high entropy=low free energy ...

Metabolism: correct answer: Catabolism + anabolism Catabolism: correct answer: Breakdown/ degradation of macromolecules = net gain of energy. -cells use energy conversion strategy that oxidizes glucose. -Small bits of energy are released at several points in the pathway called ATP (energy currency) Anabolism: correct answer: Buildup of macromolecule = loss of net energy Stages of Catabolism: correct answer: Stage 1: hydrolysis of macromolecules into smaller micro molecules/ subuni...

Term for the study of normal function and it's components - Physiology Term for the study of disease, a diseased state. Disordered physiological processes associated with disease or injury. - pathophysiology Pathologies typically result from what type of failure? - Compensation failure What is known as a group of signs and symptoms that occur together and characterize a specific disorder or condition? - Syndrome A DYNAMIC STEADY STATE (not equilibrium). Required for constant internal stab...

Two individuals of the same body mass are lifting weights. Assuming all other factors to be equal, the person with tendons inserted on the bone the joint center should be able to lift weight. closer to; a heavier medial to; less laterally to; less farther from; a heavier Question 2 3/3 pts The Krebs cycle occurs in which portion of the cell? mitochondria nucleus membrane cytoplasm Question 3 3/3 pts An athlete produced 840 watts of power in 0.6 seconds. How much work ...

Biology 2420 - Final Exam Questions And Answers Living entities, surrounded by a membrane, that are capable of growing, reproducing, responding and metabolizing are known as: A) Cells B) biofilms C) bioreactors - ANS Cells ________ contain a nucleus composed of genetic material surrounded by a membrane: A) pseudo eukaryotes B) eukaryotes C) prokaryotes D) enzymes - ANS Eukaryotes ________ cells are those that do not have a membrane-bound nucleus: A) pseudo eukaryotes B)...

Metabolism - Answer Total energy expenditure of all cata/anabolic processes (bodies ability to use fuel) Measured by either direct (calorimetry chamber) or indirect (Douglas bag/metabolic cart) calorimetry Calorimetry = measure of energy expenditure (kcals = E to heat 1kg water 1°C) Oxidation-Reduction Reaction - Answer - Are always *coupled reactions* (the energy given off by the exergonic reaction powers the endergonic reaction) - *Oxidation*: removing an electron - *Reduction*...
