Bio 198 Exam 5 Review Questions and Correct Answers

What is the function of a photosystem in plants to collect energy from the sun and use it to split water freeing high energy electrons Where in an atp molecule is energy stored and how is the energy released in the bond holding the third phosphate released by breaking the bond in an exergonic reaction What is the role of nadh and fadh2 in the process of aerobic respiration to transport energy rich electrons to the first acceptor of the electron transfer system What is the function of endocytosis and exocytosis move larger molecules into and out of the cells During class, you measured the amount of oxygen produced by plants photosynthesis under different wavelengths of light. What wavelength allowed plants to photosynthesize at the maximum rate rate and why blue, because chlorophyll absorbs mostly blue light for use in photosynthesis How do fungi gain the energy they need to survive and reproduce fungi are heterotrophs and extracellularly digest food before absorbing molecules for respiration Water flows into your cells because freshwater is _________ compared to the insides of your cells and water moves in via the process of ________ hypertonic, osmosis Which of the following organisms use aerobic cellular respiration animals, fungi The electron transfer chain of aerobic respiration is located on the ______ and it uses ______ as the final electron acceptor resulting in the production of ______ and atp molecules matrix of mitochondria, oxygen, water In class you observed the succession of bacteria found in milk over time. What process is responsible for the decrease in ph as bacterial numbers increase bacteria use aerobic respiration and fermentation to produce lactic acid, which decreases the ph What happens to the elections produced by splitting water molecules during the light-dependent reactions of photosynthesis the electrons enter photosystem 2, go through an electron transfer chain, enter photosystem 1 go through another electron transfer chain, and finally end up in nadph
