A microspore that is isolated out of a pollen sac, and given nutrients in a test tube, will develop into a pollen grain with a cell wall being the same as the cell wall of a pollen grain that develops inside of a pollen sac. Do you agree with this statement? Explain your answer
a. The membrane potential of an isolated mitochondrion was measured to be -156 mV. The pH inside of the mitochondrion was determined to be 7.2 while outside the mitochondrion it as 6.2. What is the free energy of transport for H+ into the mitochondrion? (answer should be -21 kJ) b. If the free energy of ATP synthesis is -35 kJ/...

18. (2 pts.) The equations for organic reactions usually focus on the desired transformation from reactant to product, other possible products such as byproducts and/or side products are often not included, even though it is understood that these are also formed in almost every organic reaction. Shown below is a complete equation for the ester synthesis reaction for the...
Phenolphthalein has a pKapKa of 9.7 and is colorless in its acid form and pink in its basic form. a) For pH=pH= 2.0 calculate [In−]/[HIn][In−]/[HIn]. Express your answer using two significant figures. b) Predict the color of a phenolphthalein solution. Predict the color of a phenolphthalein solution. colorless pink c) For pH=pH= 5.1 calculate [In−]/[HIn][In−]/[HIn]. Express your answer using two...
The Michaelis-Menten equation models the hyperbolic relationship
between [S] and the initial reaction rate (V0) for an enzyme
catalyzed, single substrate reaction: E S ES E P. The model can be
more readily understood when comparing three conditions: [S]Km.
Match each statement with the condition that it describes. Note:
\"Rate\" refers to initial velocity (V0) where steady state
conditions are...
QUESTION 10 In cyclic voltammetry, the current is measured versus applied potential as the potential is swept from an initial value to a new value and then back to the initial value. This is called a _ waveform A. Square wave O B. Linear OC. Pulse OD. Triangular O E. Cycle QUESTION 11 the anodic peak current is the cathodic...

The Michaelis-Menten equation models the hyperbolic relationship between [S) and the initial reaction rate V, for an enzyme-catalyzed, single-substrate reaction E+S ES E + P. The model can be more readily understood when comparing three conditions: [S] << Km, [S] = Km, and [S] >> K. Match each statement with the condition that it describes. Note that "rate" refers to...
