Which of the following is correct about turnover number (kcat) and the specificity constant for an enzyme? A. The kcat reveals how well an enzyme works.
B. kcat Vmax/[ES]
C. The specificity constant is defined as (kcat)(Km)
D. The specificity constant is defined as kcat/Km.

B

Explanation:

Specificity constant-The ratio of Kcat/Km is called as specificity constant.

 Kcat-Turn over number

 Km-Michaelis constant

Specifictiy constant is the measure of enzyme efficiency .

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
