Researchers are working to develop biofuels to free us from dependence on fossil fuels. Based on what you know about cellulose, what do you predict are the... [Show More] major advantage and disadvantage of using cellulose-rich plant material as biofuel? 2. What examples describe the second law of thermodynamics? Select all that apply. 3. Neostigmine is a drug used to treat the disease myasthenia gravis. The drug binds to the active site of acetylcholinesterase preventing breakdown of acetylcholine. This drug is a(n) 4. Glycerol and fatty acids can combine to make triglycerides. This represents a(n) 5. C6H12O6 + 6O2 ? 6H2O + 6CO2 is an example of ________________. 6. Since metabolism involves the synthesis and breakdown of non-protein cell components like mono- and polysaccharides, lipids, and ATP, there is not much role for gene mutations to influence the process. 7. How does ATP differ from a RNA nucleotide? 8. Making popsicles _____________the entropy of the system. 9. What is an example of potential energy? Select all that apply. 10. After many years of difficult research, your company invented a drug that increases the enzyme rate for the synthesis of an important metabolite. Patients with mutations in the enzyme lack the metabolite and have devastating symptoms. Your team is thrilled to have a drug that speeds up the enzymatic rate. [Show Less]
How are the membrane components oriented? 2. Molecules move from a high to low concentration in 3. What is the first step in Na+-K+ pump? 5. The i... [Show More] mpermeability of cell plasma membranes is a major barrier to using drugs to kill tumor cells or affect cells transgenically. CPPs are peptides that were discovered to have the ability to transport themselves (and even attached cargo) into cells. How they get into cells is still a mystery, but CPPs all have multiple positively charged groups. Which of the following membrane components are they most likely to be interacting with? 6. What substance would have the slowest speed of passage across a selectively permeable membrane? 7. If sodium does not move down its gradient in the co-transport pump, what would be the outcome? 8. What protein is matched with its function? 9. The fluid mosaic model describes membranes as fluid due to 10. What molecule(s) could diffuse across the plasma membrane? [Show Less]

Cardiac muscle also relies on calcium to contract. What junction is involved and what organelle stores calcium? 6. If an integrin protein is mutated what cell function might be affected? 7. Plants, fungi and bacteria all have what similarity? 8. What is the pathway in which a protein moves through the endomembrane system? 9.

Docmerit is a great platform to get and share study resources, especially the resource contributed by past students and who have done similar courses.
I find Docmerit to be authentic, easy to use and a community with quality notes and study tips. Now is my chance to help others.
University Of Arizona
One of the most useful resource available is 24/7 access to study guides and notes. It helped me a lot to clear my final semester exams.
Docmerit is super useful, because you study and make money at the same time! You even benefit from summaries made a couple of years ago.
