Statement I: During the lag phase, the cell number or biomass increases rapidly. 

Statement II: The duration of the lag phase depends mainly on the size of the inoculum and the growth phase of the source culture.

In light of the above statements, choose the correct answer from the options given below:

#Biochemistry

When a muscle is stimulated to contract aerobically, less lactic acid is formed than when it contracts anaerobically because:

#Question id: 531

#Biochemistry

Glucose labeled with ¹⁴C in C-1 and C-6 gives rise in glycolysis to pyruvate labeled in:

#Question id: 532

#Biochemistry

In glycolysis, fructose 1,6-bisphosphate is converted to two products with a standard free-energy change (DG'°) of 23.8 kJ/mol.  Under what conditions (encountered in a normal cell) will the free-energy change (DG) be negative, enabling the reaction to proceed to the right?

#Question id: 533

#Biochemistry

Glucose, labeled with 14C in different carbon atoms, is added to a crude extract of a tissue rich in the enzymes of the pentose phosphate pathway.  The most rapid production of 14CO2 will occur when the glucose is labeled in:

#Question id: 534

#Biochemistry

If glucose labeled with 14C in C-3 is metabolized to lactate via fermentation, the lactate will contain 14C in:

#Question id: 535

#Biochemistry

In some diabetic patients, glucose increases disproportionately and is unresponsive to an insulin challenge; under these conditions, how would oneʹs liver normally respond?

A) phosphorylating glucose for entry into the glycolytic pathway

B) saturating glucokinase with glucose

C) phosphorylating glucose for entry into the glycogen synthesis pathways
