C. light reactions photophosphorylate ADP, while the Calvin cycle produces ATP. Phycobiliproteins are a complex of accessory pigments and proteins found in cyanobacteria but not in green algae. Based on the information presented, how does aldosterone most likely enter target cells? 18 terms. 24 terms. AP Biology is an introductory college-level biology course. The production and secretion of proteins One thing that helps cells to be able to take care of different processes inside the cell is the membrane and organelles that have membranes as well. Question 8. Now, heat is transferred to refrigerant-134a until the temperature is 15^\circ{}C. Because the question specifies that oxygen is required, the process depicted must show aerobic respiration rather than glycolysis. The two stages of photosynthesis are the light-dependent reaction and the light-independent reaction. Others act as channels or pumps, allowing specific molecules to pass through the membrane. The AP Biology Exam is 3 hours long and is divided into two sections: Section I (multiple-choice questions) and Section II (free-response questions). Glycolysis is the first step in cell respiration and occurs with or without oxygen present and shows common ancestry. Stand alone questions on the AP Biology test are your average multiple choice question and make up a little over half of the questions in the section. The cecum evolved to have an important role in the digestion of protein, since it is shorter in species B and C than in species A and D. What is the value of KpK_pKp?
