Endothermic reactions - Study guides, Class notes & Summaries

A form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size - Binary Fission Enzymes, toxins, and other factors that affect the relative ability of a pathogen to infect and cause disease. - Virulence factors Gram staining differentiates bacteria based on their: A) ATP B) endospore C) cell wall D) integral proteins - Cell Wall Reactions that require energy are called ________ reactions: A) endergonic B) endothermic C) exergonic ...

In this section, we explore the rules of energy that we observe in the universe. We see many examples of these laws in action on a day-to- day basis. You will learn how to compare and contrast exothermic and endothermic reactions as well as the first and second laws of thermodynamics.
