Bisphenol A (BPA) binds to the estrogen receptor with a Kd of 2.1 x 10-7 M and an association rate of 1.3 x 106 M-1s-1. Compute the dissociation rate, kd, comprising appropriate units.
Cellulose could give a widely available and cheap form of glucose, however humans can't digest it. In your own words explain why cellulose can't be digested by humans.
A food manufacturer is advertising a latest cake mix as fat free. Hydrolysis of the cake mix yields glucose, glycerol, fructose and amino acids, molecules with hydrocarbon chains and a carboxyl grou
The four stages of the disposition of a toxic compound to evaluate its toxicity are absorption via membranes in a system, the distribution all through the system, the excretion and removal from the
Contained is an explanation of the signaling cascade which results from EGF stimulation of the Ras-MAPK pathway in cells.
The neuropeptide neurotransmitters are comprised in: a) Pain regulation. b) Stimulation of skeletal muscle. c) Inhibition of acetylcholine receptors. d) Mood regulation. e) Release of hormones.
What happens during neural divergence? In divergence, one neuron: a) is controlled by several neurons b) is controlled by several neurotransmitter substances
Show a complete and balanced reaction (all atoms or all bonds for structure) for the formation of diethyl ether from two ethanol molecules. (see: formation of ethers by dehydration of alcohols).
Draw the structure again (showing all bonds), and this time indicate the H bonding of dihydroxyacetone to water. Remember which atoms form H bonds -- you've seen this "rule" several times.
Draw the structure of ribose-5-phosphate (draw out ALL bonds including the bonds within the alcohol FG). Show the hydrolysis of sucrose to glucose and fructose (draw out ALL structures in the reactio

LDL particles have a higher percent content of cholesterol and cholesterol esters than VLDL particles. Describe the catabolism of the VLDL particles that occurs in the circulation and how this accou
Discuss the advantage and disadvantage of random addition or deletion of nucleotides at VDJ junctions during re-arrangement of immunoglobulin gene segments.
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.
