enzymes (lab practical)

Which of the enzymes being tested is found in peroxisomes?

catalase

how do enzymes speed up reactions without being consumed in the process?

they lower the activation energy of a reaction

SDS can inhibit the amylase reaction by

Altering hydrophobic conditions.

what is amylase?

a digestive enzyme that breaks starch down into maltose and glucosed -released from salivary glands and pancreas

what is pepsin?

a digestive protease that breaks proteins down into peptides and amino acids

If an enzyme in solution is saturated with substrate, the most effective way to obtain a faster yield of products is to

add more of the enzyme

why does a cell only need a small amount of an enzyme?

because they can be used over and over

less amylase activity color?

dark blue

Which enzyme reaction will cause a cloudy solution to clear?

lysozyme

without enzymes...

metabolism would be wayyyy to slow!

many enzymes havve optimum activity at what pH and what body temp?

neutral & normal body temp

Alkaline phosphatase + p-nitrophenol-phosphate —> ______________

p-nitophenolate

what are enzymes?

proteins that act as catalysts for biological reactions -speed up reactions

more amylase activity color?

red orange

what does t mean when an enzyme can be denatured?

that it destroys it's activity and slows the reaction

the more amylase activity there is.....

the less starch there will be

enzymes are generally ...

very specific by acting on one substrate or one class of related substrate molecules

how can you test for amylase?

with the iodine test
