BSCI 207 Unit 1 Exam Questions and Answers 100% Solved Free energy differs from total energy because: - It is available to do work. Life relies on two key reactions: the oxidation of glucose to produce CO2 and water and the reaction of CO2 and water to produce glucose. These reactions are: - Exergonic and endergonic, respectively A reaction that is exergonic AND spontaneous - Only occurs if the reactants have enough energy to get over the activation barrier When you clean your room, you...

These lecture notes provide a detailed exploration of neurons, electrical signaling, and the evolution of nervous systems. The document covers various aspects, including the evolutionary solutions that led to the development of neurons, sensory response systems, and the evolution of electrical signaling. It delves into the elements of neurons, membrane potentials, action potentials, and synaptic transmission. Additionally, the notes discuss the techniques used to measure membrane potential, the ...

BSCI207 Exam 2 Study Guide.

This document encapsulates the core concepts discussed in Lecture 21, focusing on organisms' gas exchange and circulatory systems. It elaborates on Fick’s Law and the Hagen-Poiseuille Equation, explaining how physical constraints influence the evolution of gas exchange organs and circulatory systems. Furthermore, it delves into the mathematical formulations of gas flux and flow rate, emphasizing the crucial role of concentration gradients and pressure differentials in gas exchange. The docume...
