Chapter 8: Vocabulary Adenosine Triphosphate (ATP): a molecule composed of the sugar ribose, the bases adenine, and three phosphate groups; the major energy carrier in cells. Cellular Respiration: the oxygen-requiring reactions, occurring in mitochondria, that break down the end products of glycolosis into carbon dioxide and water while capturing large amounts of energy of ATP. Chemiosmosis: a process of ATP generation in chloroplasts and mitochondria. The movement of electrons down an electron transport system is used to pump hydrogen ions across a membrane, thereby building up the concentration gradient of hydrogen ions across the membrane; the hydrogen ions diffuse back across the membrane through the pores of ATP-synthesizing enzymes; the energy of their movement down their concentration gradient drives ATP synthesis. Electron Transport Chain: Fermentation: anaerobic reactions that convert the pyruvic acid produced by the glycolysis into lactic acid or alcohol and CO2. Glycolysis: reactions, carried out in the cytoplasm, that break down glucose into two molecules of pyruvic acid, producing two ATP molecules; does not require oxygen but can proceed when oxygen is present. Intermembrane Space: The fluid filled space between the inner and outer membranes of mitochondrion. Krebs Cycle: a cyclic series of reactions, occurring in the matrix of mitochondria, in which the acetyl groups from the pyruvic acids produced by glycolysis are broken down to CO2 , accompanied by the formation of ATP and electron carriers also called citric acid cycle. Matrix: the fluid contained within the inner membrane of mitochondrion.

Chapter 40: Vocabulary Fission: asexual reproduction by dividing the body into two smaller, complete organisms. Follicle: in the ovary of female mammals, the oocyte and its surrounding accessory cells. Follicle-Stimulating Hormone (FSH): a hormone, produced by the anterior pituitary, that stimulates spermatogenesis in males and the development of the follicle in females. Genital Herpes: a sexually transmitted disease, caused by a virus, that can cause painful blisters on the genitals and surrounding skin.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
