The presence o... f a cell wall and cell membrane, but the absence of cellular organelles would be a description of which of the following classes of cells? a. prokaryotic cells b. eukaryotic cells 2. Which one of the following is a function of a protein? a. serves as an enzyme and speeds up a chemical reaction b. stores genetic material and enables its transmission to the next generation c. provides energy for a muscle contraction d. is a primary structural component of DNA 3. Which of the following molecules is broken down as a result of the metabolic process known as glycolysis? a. pyruvate b. carbon dioxide c. glucose d. ATP 4. The purpose of the Krebs cycle is to produce high energy carrier molecules like NADH and FADH2 that then feed into the electron transport chain. During this process, another by-product molecule is produced. Which molecule is produced during the Krebs cycle? Hint: the Krebs cycle is part of aerobic respiration. a. water b. carbon dioxide c. lipids d. glucose Question 5 2 / 2 pts One of the end products of glycolysis is: fructose glucose carbon dioxide pyruvate Question 7 0 / 2 pts The purpose of glycolysis and the Krebs cycle is to use split glucose to harness the energy in the bonds thereby generating high energy molecules that feed electrons into the electron transport chain. If an organisms has a defect in an electron chain molecule but can complete glycolysis, would the organism be able to survive? No, the organism would not be able to produce any energy. No, the organism would not be able to control the large amount of energy produced. Yes, although the organism may be limited in size because only a small amount of energy is produced. Yes, although the organism would not have any way of controlling the large amount of energy produced.  wrong Question 8 2 / 2 pts Which of the following is an incorrect base pairing for DNA? cytosine - guanine adenine-thymine adenine- urocil thymine - adenine Question 9 2 / 2 pts Fill in the missing term in the following sequence: A gene comprised of DNA is transcribed to make messenger ________ which is then translated to protein. DNA enzyme RNA ATP Question 10 2 / 2 pts The energy molecule produced as a result of cellular respiration is: ATP fat GTP dNTP Question 11 2 / 2 pts The type of bond that holds together two amino acids in a protein (polypeptide chain) is called: lipidosidic peptide rolltide aminocidic Question 12 2 / 2 pts When two macromolecules are joined by a covalent bond during a biochemical reaction, a(n) ______________ molecule is given off by a process called condensation or dehydration synthesis. ATP water ADP coenzyme Question 13 2 / 2 pts In which of the following would you find lipids? applesauce butter water diet soft drinks Question 14 2 / 2 pts In cellular respiration, most of the ATP's are produced during which process? electron transport reaction photosynthesis Krebs cycle fermentation glycolysis Question 15 0 / 2 pts Which of the following molecules is used directly within the cell to perform functions that require energy: Protein  wrong fats ATP carbohydrates [Show More]
