AP biology stands for advanced placement biology. AP is similar to the IB, international baccalaureate, exam. It allows high school students to take college level classes without being in college. Most accredited university in the United States accept AP credits so that students can take more advanced classes as college freshmen. Most schools require a certain score so that students can place
. into higher classes.Usually, the ninth chapter of AP biology covers cellular respiration. The order of instruction of AP biology is not regulated. However, professors are expected to cover a certain amount of information before the AP biology exam, so teachers often have similar teaching syllabi. Cellular respiration is one of the most difficult concepts to understand in biology because it requires the integration of many different topics including biochemistry and cellular biology.Cellular respiration occurs in different parts of the cell including the mitochondrion and parts of the cellular matrix, The study of cellular respiration is usually coupled with photosynthesis, or the process by which plants convert solar energy into sugar that they can use in cellular respiration.In cellular respiration the cell takes glucose and converts it into energy that the cell can use to make energy, in the form of ATP, adenosine triphosphate, to function. Cellular respiration is divided into two different types of respiration. The first is anaerobic respiration, which does not require oxygen. Certain organisms, such as bacteria perform anaerobic respiration through fermentation. Fermentation produces alcohol and is used by yeast. People use this to ferment different fruit juices to make alcoholic beverages. Mammilian cells perform lactic acid fermentation in anaerobic conditions. Lactic acid fermentation is the process by which muscles become tired during exercise.Aerobic respiration requires respiration and makes use of the electron transport chain. It requires that the cell have mitochondria. Aerobic respiration makes more energy than anaerobic respiration, so allows larger organisms to make energy.
