AleksAgata [21]

Answer: An increase in the ratio of insulin to glucagon will increase the activity of --

- Acetyl-CoA carboxylase(+)

-Phosphofructokinase PFK2(+)

-Glycogen synthase(+)

When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.

how much heat is needed to raise the temperature of 75 g of a substance by 15 C when the specific heat is 0.92 J/g-C?
IRINA_888 [86]
Answer is: 1035 joules of heat is needed.<span>
m(substance</span>) = 75 g.<span>
ΔT(substance</span>) = 15°C.<span>
cp(substance</span>) = 0,92 J/g°C.<span>
Q = m</span>(substance) · ΔT(substance) · cp(substance).<span>
Q = 75 g · </span>15°C · 0,92 J/g°C<span>.
Q = 1035 J = 1,035 kJ.</span>
