Macromolecules
Four types of macromolecules.
What are carbohydrates, lipids, proteins, and nucleic acids?
Sum total of all chemical reactions that take place in an organism
What is metabolism?
A weak interaction between polar molecules
What is a Hydrogen Bond?
Three kinds of sugars that Carbohydrates are broken down into.
What are Monosaccharide, Disaccharide, and Polysaccharide?
Two different types of fats
What are saturated and unsaturated?
macromolecule used for quick energy. End in letters -ose.
What are carbohydrates?
Input of energy required for all reactions
What is activation energy?
Water molecules sticking to other water molecules
What is cohesion?
Name of when a protein loses its shape and no longer works.
What is Denaturing?
Difference between polar and nonpolar covalent Bonds.
What is polar share unequally and nonpolar share equally?
Fats, oils and waxes are this type of macromolecule. This macromolecule stores energy, cushions and protects and is used for insulation.
What are lipids?
Speeds up a reaction by lowering the activation energy
What is a catalyst?
When water can stick to other things but only polar things.
What is adhesion?
Measure of how acidic or basic something is, from 0-14
What is pH?
Difference between a solute and a solvent
What is a solute is the material being dissolved and a solvent is the substance doing the dissolving?
Make up a large part of the human body; meats and nuts in diet
What are Proteins?
Protein catalysts that speed up reactions are called ___________.
What are enzymes?
Energy needed for water to change temperature; even more energy is needed for it to change states of matter
What is specific heat capacity?
A base is less than ____, an acid is greater than _______ and Neutral is ______
What is 7?
A molecule that resists pH changes; helps the body maintain homeostasis.
What is a buffer?
Monomer is a nucleotide; Stores information and pretty much runs the cell
What are Nucleic Acids?
Describe lock and key model.
What is where a substrate enters an active site, slightly changes shape as it binds, reduces activation energy and then the products leave the active site on the enzyme?
Combines adhesion and cohesion to move up against gravity; we see it in plants
What is capillary action?
Environmental influences that affect optimum rate of enzymes are __________________ (There are 3)
What are Temperature, Substrate Concentration and pH?
Cells create "pockets" where enzymes are concentrated and do specific functions.
What is compartmentalization?
