Q. 16.73 - An Introduction to General, Organic, and Biological Chemistry

Question

 Indicate whether eachof the following would be a substrate $\left(S\right)$or an enzyme $\left(E\right):$ $(16.4)$

$a.$ lactose

$b.$ lipase

$c.$ amylase

$d.$ trypsin

$e.$ pyruvate

$f.$ transaminase

Step-by-Step Solution

Answer

Enzymes are organic catalysts which catalyze numerous chemical reactions in dwelling systems. 

Step 1: Introduction.

                      Enzymes are the proteins, which lower the activation power of response and catalyse the response process. 

                     An worldwide committee set up a technique for naming the enzymes, Which is primarily based totally on their function. 

                    The call of every enzyme ends with a suffix, -ase. 

                    The older enzymes pepsin, trypsin and renin are exceptions. 

Step 2: Given Information.

Different enzyme classes consist of

                     - Hydrolases (carryout hydrolysis reactions, $eg:$ protease, lipase, nuclease, phosphatases) 

                     - Transferases (switch a set among $2$ compounds, $eg:$ kinases, transaminases)

                     - Oxidoreductases (oxidation-discount reaction, $eg:$oxidases, reductases, dehydrogenases) 

                     - Lyases (upload or take away organizations concerning double bonds, however does now no longer consist of hydrolysis, $eg:$ carboxylases, deaminases) 

                     - Ligases (join  molecules with the aid of using the usage of ATP, $eg:$ synthetases) 

                     - Isomerases (rearrange atoms in a molecule, $eg:$ Isomerases, epimerases) 

Step 3: Explanation.

$\left(a\right).$ Lactose - Substrate (lactase hydrolyzes lactose)

$\left(b\right).$ Lipase - Enzyme (Hydrolyzes lipids)

$\left(c\right).$ Amylase - Enzyme (hydrolyze amylose)

$\left(d\right).$ Trypsin - Enzyme (hydrolyzes proteins)

$\left(e\right).$ Pyruvate - Substrate (glucose is converted into pyruvate during glycolysis)

$\left(f\right).$ Transaminase - Enzyme (catalyse transamination reaction)
