Answer:
a1) Direction is from B to C
a2) Rate of activity = 10pmol/10⁶ cells
b1) Activity rate = 45 pmol of C created/10⁶ cells
b2) Activity rate= 44 pmol of B created/ 10⁶ of cells
b3) Activity rate = 80 pmol of B created/ 10⁶ of cells
Explanation:
a) E1 = 50 pmol of C
E2 = 40 pmol of B
Since E1 is greater than E2, the direction is from B to C
Rate of activity: 50pmol/10⁶ cells[B] - 40pmol/10⁶[C]
Rate of activity = 10pmol/10⁶ cells
b1) Activity of E1 reduced by 10%
Activity rate= 50 - 10% of 50
Activity rate= 50 -5
Activity rate = 45 pmol of C created/10⁶ cells
b2) Activity of E2 increased by 10%
Activity rate = E2 + 10% of E2
Activity rate= 40 + 10% of 40
Activity rate= 40 + 4
Activity rate= 44 pmol of B created/ 10⁶ of cells
b3) The activity of E2 is doubled
Activity rate = 2 * E2
Activity rate = 2 * 40
Activity rate = 80 pmol of B created/ 10⁶ of cells
