Answer:
A metabolic pathway
Explanation:
Biologically, a metabolic pathway is a series of chemical reactions in which the end product of a reaction serves as a substrate (or reagent) for the reaction thereafter, the reactions being interdependent with one another. These reactions are catalyzed by enzymes. The metabolic pathways are fundamental for the maintenance of the cell and consequently of the body's homeostasis.
An example of the metabolic pathway can be seen in the above question where glucose is converted to glucose 6-phosphate by hexokinase. Glucose 6-phosphate then serves as a substrate for the enzyme phosphoglucose isomerase, which converts this reagent to fructose 6-phosphate. Fructose 6-phosphate serves as a substrate for phosphofructokinase, which converts fructose 6-phosphate into fructose 1,6-bisphosphate.
Answer:
The mass of the liquid = 162 g
Explanation:
As we know ,
Q = mc (ΔT)
where Q = Heat energy of the liquid
c = specific heat of the liquid
ΔT = change in temperature
m = mass of the liquid
As given , the temperature increases from 20.°C to 33°C,
⇒ ΔT = 33 - 20 = 13°C
Also given , c = 0.57 cal/g°C
Q = 1200 cal
∴ we get
1200 = (m)(0.57)(13)
⇒ 1200 = m(7.41)
⇒m = = 161.943 ≈ 162 g
So, we get
The mass of the liquid = 162 g
The balanced chemical reaction is:
2NaClO3 9= 2NaCl + 3O2
We are given the amount of sodium chlorate to heat. This will be the starting point of our calculations.
200 g NaClO3 (1 mol / 106.44 g) ( 3 mol O2 / 2 mol NaClO3) (32 g O2 / 1 mol O2) = 90.19 g O2
