What was gone over in Pre AP/honors Biology 1-2.
19 Terms
1
What are enzyme’s function?
To speed up a chemical reaction in substrate.
New cards
2
What is a monomer?
a molecule that can be bonded with other molecules to form polymer.
New cards
3
What is monosaccharide, disaccharide, and polysaccharide?
monosaccharide is one saccharide, disaccharide is two saccharide, and polysaccharide is more then two/many saccharide.
New cards
4
What is substrate?
the substance that enzymes alter.
New cards
5
Define an active site.
The site of the enzyme that catches/temporarily bonds with the substrate in order to speed up the chemical reaction.
New cards
6
Define the word denature.
When an enzyme is affected by high/low temperatures, and/or high/low pH. This causes it to have difficulty bonding with substrates.
New cards
7
What are the functions of lipids?
they store energy, control hormones, and cushion vital organs.
New cards
8
What are the functions of nucleic acids?
they store and express genetic information.
New cards
9
what are the functions of carbohydrates?
used to provide and store energy, and is part of the cell membrane.
New cards
10
what are the functions of proteins?
They store energy, repair and build tissues, helps structure, function, and regulation of the body’s organs, and it copies and stores DNA.
New cards
11
What are/is the monomer(s) of nucleic acids?
nucleotide.
New cards
12
What is the monomer of carbohydrates?
monosaccharide.
New cards
13
What is the monomer of protein?
amino acids
New cards
14
Which foods contain lipids?
meat, poultry, fish, seeds, nuts, and plant oils.
New cards
15
Which foods contain nucleic acids?
Every living thing has these.
New cards
16
What foods contain carbohydrates?
grains, vegetables, fruit, and dairy.
New cards
17
Which foods contain protein?
poultry, fish, seafood, and dairy.
New cards
18
How is the function of an enzyme affected by temperature?
Raising the temperature generally speeds up the chemical reaction, and lower temperature generally slows down the reaction. Above the specific temperature range, the enzymes begin to denature, resulting in less collisions with substrate.
New cards
19
How is the function of an enzyme affected by pH?
When the charges of amino acids change, the enzyme changes shape due to it, though this shape may not be effective.
