300
List the 4 types of macromolecules.
What are: 1. proteins 2. lipids 3. carbohydrates 4. nucleic acids
300
The minimum amount of energy needed for reactants to form products in a chemical reaction. In a graph this means going from a "mountain" to a "hill".
What is activation energy. (Ea)
300
If something has a pH of 7.003 what is it considered on the pH scale?
What is a VERY WEAK BASE!!
300
Can the bonds of a compound be broken down?
Yes, a compound consists of more than one type of element.
300
The best or most suitable conditions at which an enzyme has the highest activity.
What is optimum or optimal.
400
What is the monomer of carbohydrates? Hint: Think of saccharides.
What is monosaccharides.
400
If lactose binds to lactase at the active site, which is the substrate and which is the enzyme? DOUBLE JEOPARDY... What occurs at the active site?
Lactose- substrate Lactase- Enzyme The active site is where the substrate binds to the enzyme and the chemical reaction occurs.
400
What is the strongest base on the pH scale?
What is 14.
400
When atoms share electrons, what type of bond do they form?
What is a covalent bond.
400
Substance that speeds up a chemical reaction by lowering the activation energy. (i am not looking for the word enzyme)
What is catalyst.
500
Provide an example of the function or where to find each of the four macromolecules?
open ended
500
What is the difference between the lock and key model of an enzyme and the induced fit model?
Lock and Key- the lock (enzyme) and key(substrate) do not change shape Induced Fit- When the enzyme binds to a substrate, the enzyme's active site actually changes shape so that it gets the best fit around the substrate
500
If a solution releases more hydroxyl (OH-) ions than Hydrogen (H+) ions, what is its pH?
What is a base.
500
What type of chemical bond is formed from oppositely charged atoms?
What is an ionic bond.
