You can assume that any neurotransmitter could be a hormone (stored and released by an endocrine gland), and that any hormone could be a neurotransmitter (stored and released from synaptic vesicles)
What energy transformations occur between glucose and ATP? The energy in glucose is transformed into the energy stored in the chemical bonds of ATP by the oxidation of glucose during three steps of
If I use primers to flank both sides of my target DNA and then use restriction enzyme, do I want the enzyme to cut around the target DNA sequence and not the sequence itself?
Carbohydrates, lipids, and proteins are important biomolecules. Describe the structures and properties of carbohydrates, lipids, and proteins including the different forms of these biomolecules that
State the key products of the Kreb's Cycle and how many of each there are starting from 1 glucose molecule. Show how each stage of cellular respirtion contributes to the total of 38 ATP from 1 molecul
How does the temperature affect the actions of enzymes upon their substrates? Are there any other factors that could affect these actions on the substrates?
Myelin is important for action potential propagation. Multiple sclerosis is an autoimmune disease where the myelin sheath surrounding CNS axons is progressively lost.
Design and carry out an experiment in which you will test the effects of acidic fluid on enzymatic activity. 1) What question are you asking? Clearly state your hypothesis. Describe your IV and DV.
1) Is a catalase test performed on colonies from a BAP? State reasons to support your answer? 2) Explain how a catalase test helps in distinguish between Staphylococcus from Streptococcus sp.
Find out a media piece which recognizes the basic concepts of chemistry in biology and explain how it helps to better understand how basic concepts of chemistry influence biology.
1) Why is it significant to smear the blood as soon as the drop is placed on the slide? 2) Name the three factors which find out the thickness of the smear.
For an upcoming experiment, an immunoassay (ELISA) protocol calls for a complicated series of dilution steps for your blood specimen. Compute the final dilution factor after the given steps:
Define the term fatty acid oxidation and synthesis in the animal tissues. Your definitions must point out the similarities and differences of oxidation and synthesis.
A new drug was found to reduce Hepatitis B virus. The drug is an analogue of one of the nucleic acid bases of DNA and most likely works by being incorporated into the virus and disrupting viral gene
Throughout a heart attack, blood flowing to the heart muscle is interrupted by the blockage of a coronary artery. Explain how would you expect the metabolism in the heart to change?
Explain how many can the predictions above be used to find out the method by which the fatty acids are discharged from the fatty acid synthetase?
What are the ketone bodies? Explain why do they have that name, and how do they occur in metabolism? Describe why they accumulate under conditions of carbohydrate starvation or in diabetes.
I am wondering if there could be another solution which could be used to make the one to one solution, such as distilled water, or if the NaCl solution has a special role in the ionization?
