What is the substance on which the enzymes works?
A substrate
What small organic molecules works with enzymes to facilitate the enzyme activity?
coenzymes
What creates a unit that works its way along joining amino acids together?
enzymes do this, or the great aid of enzymes is how they are joined. the "unit" would be the enzymes, who created the unit? dont know, mother nature? rRNA
Which enzymes are at work during digestion?
During digestion the enzyme in saliva works on cooked food
Does the enzymes act in the mouth or in the stomach?
Both. Salivary amylase works in your mouth, and the others in your stomach and duodenum.
How does the lock and key help analogy explain enzymes?
just like keys will open a particular lock, enzymes will catalyse only a particular reaction.
What factors affect the activity of enzymes?
Enzymes work best in the pH and temperature that they are " designed " for. A pepsin enzyme works best in the low pH environment of the stomach, while amylase works best at mouth temperature and ~ 7 pH. Heat and out of range pH can denature enzymes and not only affect their activity but inactivate them.
What kind of organic compound is anyhdrase?
Enzymes. The name of an enzyme usually ends with an -ase, and start with the substrate it works with.
What organs does the pancreas work with?
It works with faeces and urine like you do!
How does the body breakdown food?
By enzymes, The way in which enzymes actually work is extremely complicated so we use the models to think about them. A good model tries to represent the known facts about something. A model about digestive enzymes needs to try to represent these facts: · Enzymes turn large molecules into smaller ones. · Enzymes do not get used up as they carry out their tasks. · Enzymes change shape as they work. · Each enzyme only works on one particular type of molecule.
What is the substance that a catalyst works on?
The substrate on which a catalyst works is called its substrate
All enzymes act best at a pH close neutral?
This is not true. Different enzymes thrive in completely different pH conditions. Consider the protease pepsin, which works in the stomach. It breaks down proteins in acidities as low as pH 2. In the duodenum, lipase works best in slightly alkaline conditions.
