it is true that a eukaryotic cell. contains structures called organelles Eukaryotic cells contain organelles and histones, they have a well-defined nucleus, and are larger than prokaryotic cells. The function of a histone found in a eukaryotic cell focuses on cellular deoxyribonucleic acid (DNA) folding The histones are binding proteins that cause the supercoiling of DNA into chromosomes and do not affect cellular division, movement, or activities. An organelle that is responsible for th...

BIOD 171/ 171 PORTAGE LEARNING (2 VERSIONS) FINAL EXAM WITH VERIFIED QUESTIONS AND ANSWERS VERSION 1 • Define catabolism. It is a process that allows larger molecules to be broken down into useful energy sources. • Upon cellular injury, which metabolic process is involved during the growth and repair phases of the cell? The anabolic process because it is involved with building up small complexes into larger complexes. • True or False: Metabolism is a controlled set of biochemi...

2 ways phosphate addition/removal causes conformational changes - Answer 1)Phosphorylation has a lot of negative charges that interfere with interactions between substrates --> forces protein into different conformations 2) phosphorylation of an enzyme can also alter substrate-binding affinity via electrostatic repulsion what happens to the GPCR and g-protein when a hormone reaches the GPCR receptor on cell membrane? - Answer hormone triggers a conformational change in receptor, which s...

AP BIOLOGY UNIT 2 TEST QUESTIONS WITH VERIFIED ANSWERS Compare and contrast P2 and P1. Photosystem II begins , which absorbs wavelengths at a wavelength of 680 nm. Here, energy is absorbed and passed along until it reaches P680 chlorophyll. When this chlorophyll is excited, it sends its electrons to the primary electron acceptor. Electrons are taken from H2O and passed to P680 to replace the electrons given to the primary acceptor. This forces O2 to form. The electrons are passed to ph...

Which two of the following statements are correct regarding the Embden-Meyerhof pathway? - Answer It can occur in the absence of oxygen It results in glucose degredation In substrate-level phosphorylation, ATP production is coupled with ______. - Answer hydrolysis of a molecule with a higher phosphate transfer potential than ATP
