What is the biological significance of the temperature at which the amylase catalyzed reaction
ipn [44]

Answer:

The biological significance is that it is the normal human body temperature and also the optimum temperature of the enzyme.

Explanation:

  • Enzymes are biological catalysts that speed up the rate of chemical reactions.
  • Enzymes catalyze specific reactions by working on a specific substrate to convert it into a product.
  • The rate of enzyme activity depends on several factors which include pH, temperature, substrate concentration, and enzyme concentration among others.
  • Enzymes work best at a specific pH and temperature known as optimum pH and optimum temperature respectively.
  • In this case, enzyme amylase works best at a temperature of 37° C which is equivalent to the normal human body temperature.

Given the balanced equation: 2KClO₃ ---&gt; 2KCl + 3O₂ How many moles of O₂ are produced when 4.0 moles of KCl are produced?
Verizon [17]

Answer:

The answer to your question is 6.0 moles of O₂

Explanation:

Data

                      2KClO₃    ⇒     2KCl    +    3O₂

moles of O₂ = ?

moles of KCl = 4

Process

To find the number of moles of O₂, use proportions and cross multiplication.

Use the coefficients of the balanced equation.

                    2 moles of KCl ----------------- 3 moles of O₂

                    4 moles of KCl -----------------  x

                          x = (4 x 3) / 2

-Simplification

                          x = 12/2

-Result

                        x = 6 moles of O₂

-Conclusion

When 4,0 moles of KCl are produced, 6.0 moles of O₂ will be produced.
