Biochemistry- Which of the following is true?
A. The Vmax is reached when the concentration of substrate is
double the Km.
B. The Km value decreases in the presence of a competitive
inhibitor.
C. At high substrate levels the reaction velocity increases in a
linear manner with increasing S concentration
D. At very low substrate levels doubling the S concentration
nearly doubles the observed reaction rate so that the rate
increases in a linear manner.
E. When the substrate level...
An enzyme catalyzed reaction has a Km of 3.76 mM and a Vmax of
6.72 nM/s. What is the reaction velocity in nM/s,
when the substrate concentrations are:
A. 0.500 mM
B. 15.6 mM
C. 252 mM
D. Now assume you have added a competitive inhibitor that has a
concentration of 15.6 µM with a KI of 7.30 µM to the
enzyme in question 9. Calculate the velocity at the same substrate
concentrations as above:
E. 0.500 mM
F. 15.6...
A reversible inhibitor I is competitive with the substrate S
when both have
equal 1/Vmax
c. equal 1/Vmax & 1/KM
equal 1/KM
d. equal slope
A reversible inhibitor I is uncompetitive with the substrate S
when both have
equal 1/Vmax
c. different 1/Vmax & 1/KM
equal 1/KM
d. different slope
1. Which of the following is true of the
calculation of equivalent units when there is nonuniform
application of manufacturing inputs?
Equivalent units are calculated using weighted average cost
method only.
The ending work in process is ignored in the calculation of
equivalent units.
Equivalent cost of ending work in process is considered as the
equivalent cost throughout the period.
Equivalent units are calculated for each category of
manufacturing input.

Which of the following statements is/are TRUE? (i.e. select ONLY
the answer(s) that is/are TRUE.)
1.RNA polymerase does not require primer to initiate the process
of assembly of nucleotide triphosphates. This is in contrast to DNA
replication, where primer is required at initiation.
2.The addition of a Poly-A tail on the end of a transcript
happens because of the transcription of the Poly-T signal from the
corresponding gene.
3.The molecule Poly-A polymerase is responsible for addition of
the Poly-A sequence...
Which of the following is a type 1 error?
a. When H0is true and H0 is accepted
b. When Hais true and H0 is accepted
c. When H0is true and Ha is accepted
d. When Hais true and Ha is accepted
1. Which of the following is not true?
A) when a series has the same average growth rate from period to
period, then it can be approximated by including trend in a
regression.
B) dummy variables can be used to address the problem of
seasonality in regression models.
C) yt = α0 + β0st + β1st−1 + β2st−2 + β3st−3 +ut , it is
possible to estimate long-run effect of change in st on yt .
D) serial correlation of...
1. Which of the following statements is true of
the accounting for finished goods when a job is completed?
Overhead costs are assigned to Finished Goods using a
predetermined rate.
Finished Goods is debited when goods are sold.
The cost of completed units is credited to Work-in-Process and
debited to Finished Goods.
The costs of the completed job are retained in Work-in-Process
until the proceeds are collectible for the job.
