18 Questions
What is the effect of exposing enzymes to very high temperature?
It causes denaturation, an irreversible process
Why is the specific shape of enzymes important for their function?
It ensures the substrate will fit into the active site
What happens if the pH deviates significantly from the optimum pH for an enzyme?
The enzyme will denature, causing a loss of activity
What does amylase enzyme digest starch into?
Maltose, a disaccharide of glucose
What is the role of enzymes in living organisms?
Enzymes maintain reaction speeds of metabolic reactions to sustain life
What is the relationship between enzymes and substrates?
Enzymes have specific active sites that bind with complementary substrates
What happens to the products after a reaction occurs in the enzyme's active site?
The products leave the enzyme's active site as they no longer fit
How do enzymes and substrates move about in solution?
Enzymes and substrates randomly move about in solution
What is the role of enzymes in metabolic reactions?
To maintain reaction speeds at a rate that can sustain life
What is the relationship between the shape of the active site and the substrate?
The shape of the active site is complementary to the 3-D shape of the substrate
What occurs when the substrate moves into the enzyme's active site?
They form the enzymes-substrate complex
What happens to the products after a reaction occurs in the enzyme's active site?
They leave the enzyme's active site as they no longer fit
How do enzymes and substrates move about in solution?
Randomly
What is the effect of exposing enzymes to very high temperature?
It causes the bonds in the enzyme to break, known as denaturation
What is the optimum pH for most enzymes?
pH 7
What is the role of iodine solution in testing for starch?
It turns blue-black in the presence of starch
What is the irreversible effect of denaturation on enzymes?
It alters the enzyme's shape and leads to loss of function
What is the function of amylase enzyme?
To digest starch into maltose
