Different enzymes are most efficient at different temperatures, these are called 'the optimum temperature'. A temperature far lower than this will cause the rate of reaction to slow until barely noticable. A temperatuere far higher than this will cause the shape of the enzyme to change and the enzyme will become denatured.

Are the products of sucrose hydrolysis reducing sugars?
No, sucrose is not a reducing agent. The disaccharide sucrose can be 'inverted' breaking the molecule into the monosaccharides glucose and fructose, both of which are reducing sugars. This is commonly done by enzymatic action.
Why does the pH of a fatty solution decrease as enzymatic hydrolysis increases?
During enzymatic cleavage, hydrogen atoms/protons are released into the solution causing the pH to drop to build up of protons.
Enzymes are usually inactivated at what temperature?
The optimal range for the enzymatic activity goes from 25oC to 32oC.
Nucleic acids capable of catalyzing some types of enzymatic reactions?
RNA
Would the pH of the solution be lower before or after the enzymatic reaction?
It would be higher
What temperature promotes enzymatic action?
37C
What promotes enzymatic action?
37C
Does enzymatic action in a chemical reaction result in an increase in temperature?
Yes it can, but more commonly an increase in temperature increases enzymatic action.
Enzymatic reactions can be controlled by?
pH. salinity. temperature. hormones.
Does temperatures influence enzymatic browning?
Temperature does affect enzymatic function - temperature affects the "active site" of the enzyme and so the substrate cannot bind to it anymore (process is called denaturation)
How can heat prevent microbes from growing?
If it's hot enough, then various proteins are denatured (broken down) - even before then the efficiency of the enzymatic action of proteins is often temperature dependent.
Which factors is utilized by cells to regulate enzymatic reactions?
temperature and pH
What 2 conditions might change the rate of an enzymatic reaction?
pH and temperature
Do peroxisomes function to digest particles ingested by endocytosis?
no they are able to detoxify substances by enzymatic action
Which of the following digestive functions can occur in the mouth A Enzymatic action on protein B Absorption of water C Enzymatic action on carbohydrates D Secretion of bile?
C. Your mouth contains the enzyme amylase, which will breakdown starches (carbohydrates). (Web and Textbook sources).
What are the 2 conditions that destroy enzymatic activity by bond breakage?
1) Temperature 2)pH
What is type of feedback in which a given action promotes more of the same?
The type of feedback that promotes more of the same action is positive feedback. It occurs when the result or outcome of an action increases the likelihood of that action being repeated or continued. Positive feedback reinforces and encourages the behavior or action that produced it.
