Caculate the number if moles of the following: 800. g of Ca
Maru [420]
Mole   is  equal  to   mass  of  the  element  divided  by   molar  mass  of  the  element.  that   is
mole=mass/molar  mass
From  periodic  table calcium  has  a   molar  mass  of  40   g/mol
moles  is   therefore  =800g/40g/mol=20moles

A deficiency in thiamine (TPP) will directly decrease the activity of which of the following enzymes? a. Pyruvate carboxylase b.
Blababa [14]

Answer:

d. Transketolase

Explanation:

Transketolase utilize thiamine diphosphate (ThDP) as cofactor has reduced activity during the thiamine deficiency and results in the tissue damage. <u>The levels of steady-state mRNA of transketolase in human lymphoblasts, fibroblasts and neuroblastoma cells are found to be lower in the thiamine-deficient cultures.  </u>

Thus, deficiency in TPP directly decrease the activity of enzyme, transketolase.

True or
VashaNatasha [74]

This statement is True. If the temperature of this system is increased, the concentration of carbon monoxide decreases.

The principle [a] dictates that we should raise the temperature at a constant volume in order to increase the concentration of CO2 because it is an endothermic reaction.

[b] Because there are equal numbers of reactions and products in the reaction, the condition of equilibrium cannot be affected by a change in volume.

[c] As reaction concentration rises, equilibrium moves in favor of the product and the concentration of the products, which results in an increase in CO2
