8. a solution of an enzyme and a substrate
was placed in a water bath and the
temperature of the reaction was raised
gradually. the graph shown was plotted at
the end of the experiment.

what can be concluded from the graph?
o emperature has no effect on the activity of
the enzyme.
the enzyme shows increased activity up to a
certain temperature.
the effect of temperature on the enzyme is
unpredictable.
o
the activity of the enzyme is inversely
proportional to the temperature.

The enzyme shows increased activity up to a certain temperature.

Explanation:

An enzyme is mostly a protein molecule/a biologist catalyst that speeds up the rate of a chemical reaction in a cell.

Enzymes lower the reaction's activation energy by attaching to the reactant molecule and positioning itself in a manner that readily facilitates chemical-bond breaking and forming process.

As the temperature increases, the rate of enzyme catalyzed reaction increases up to a maximum level (optimum temperature) and then decreases abruptly with any further temperature increase.This optimum temperature is 40°C for most animal enzymes.The abrupt decline in the rate of reaction after the optimum temperature is caused by the denaturing of enzymes by temperatures above 40°C.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up

synapse nervous system
