AC-HPAT Biology Prep Questions and Answers Already Passed Most of the cell membrane's specific functions are controlled by: Proteins Alcoholic Fermentation is a form of: Anaerobic Respiration Phagocytosis is a form of: Endocytosis What is a pyruvate? Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. One molecule of glucose breaks down into two molecules of pyruvate, which are then used to provide furth...

DNA Replication - ANSWERDNA helicase breaks hydrogen bonds. Each strand acts as a template. Free nucleotides attach. Complementary base pairing occurs- AT and CG. DNA polymerase joins nucleotides. Hydrogen bonds reform. Semi-conservative replication- new DNA molecule contains one old and one new strand Transcription - ANSWERDNA helicase breaks hydrogen bonds between DNA strands. One strand acts as a template. RNA nucleotides attract to exposed complementary bases on DNA. RNA polymerase joins ...

WGU C785 Preparedness baseline Exam knowledge Test Questions with A+ rated Marking scheme Latest 2024 How does the activation energy of enzyme-catalyzed reactions compare to those of corresponding uncatalyzed reactions? - correct answer The activation energy of enzyme-catalyzed reactions is lower than the uncatalyzed reaction The activation energy is the amount of energy needed to get the reaction started and over the energy hill to form products. Enzymes reduce the amount of energy needed...

Which, if any, of the following statements is false, regarding the sources of genetic variation? A. Most of the inherited changes in our DNA arise because of exposure to extracellular mutagens, including radiation sources and chemical mutagens. B. Most of the inherited changes in our DNA arise because of unavoidable endogenous errors in cellular mechanisms and harmful effects of certain natural molecules and atoms within our cells. C. Errors in DNA replication and DNA repair are a major...
