Sanger sequencing functions by adding these kind of molecules to terminate replication.
What are dideoxy Nucleotide tri-phosphates
A enzymatic reaction with a competitive inhibitor lowers this part of the M-M equation with an alpha term.
What is Km?
What is this sugar based on its Fischer structure? [See slideshow].
What is L-gulose?
The general form of the membrane transport equation can be described as this.
What is G=RTln(c2/c1)+zfE
The experiments of Chargaff found that these pairs of nucleotides were found in equal amounts across different organisms.
What are A=T and G=C?
The name and linkage of this disaccharide is this. [See slideshow].
What is sucrose in an a1-2b linkage?
The Lineweaver-Burk plot is found by doing this to the M-M equation.
What is taking the double reciprocal?
What is this sugar based on its Haworth projection?
What is a-D-Galactofuranose?
The absolute and relative configuration of this molecule are said to be this. [See Slideshow].
What are L and R?
A cytidylate is a molecule that has smaller components of these groups.
What are a 5 carbon sugar (ribose or deoxyribose), a cytosine group, and one phosphate?
A single-substrate enzyme that obeys Michaelis-Menten kinetics displays the following parameters: Km = 3.4 mM; Kd = 5.7 M, and the rate constant k1 = 1 108 M-1 s-1. Given this information, what is the value of the rate constant kcat? Report your answer to the nearest ones. The units are understood to be reciprocal seconds. E+S<->ES-->E+P
What is (approx) 340,000?
This Lineweaver-Burk plot can be accurately described as this kind of inhibition. [see slideshow.]
What is a perfectly noncompetitive inhibitor?
A reducing center of a sugar is this numbered sugar.
What is Carbon 1 (or the anomeric carbon)?
The sodium potassium pump transports 5 ions for every molecule of ATP that is hydrolyzed: 3 Na+ out of the cell and 2 K+ into the cell. The pump maintains internal Na+ at 12 mM and external Na+ at 143 mM; it maintains internal K+ at 138 mM and external K+ at 7 mM. Assuming that the membrane potential is –64 mV (inside negative relative to outside), the temperature is 37 °C, and F is 23.1 kcal/V·mol, the amount of energy it takes to run this pump is this.
What is 9.7?
This nucleotide can be identified as this. [See slideshow].
What is guanine?
An uncatalyzed reaction has a rate of 4.2x10^-7 s–1 at room temperature (25 °C). When an enzyme is added the rate is 3.2 x10^4 s–1. If the height of the activation barrier for the uncatalyzed rate is 29.5 kcal/mol, what is the height of the activation barrier for the catalyzed rate? Report your answer in terms of kcal/mol to the nearest tenths. Also, assume the pre-exponential terms for the uncatalyzed and catalyzed reactions are the same. [See slideshow].
What is 14.7kcal/mol?
