Flashcards in Unit 1: Cells Deck (57)
What is oxygen's partial charge in water and why
It has a partial negative charge bc of its greater electronegativity
Measure of hydroxide ion concentration
Molecules that are carbon and hydrogen based
Why can carbon make complex structures?
Bc it can bond four times due to its high electronegativity
Four Organic Compounds
Carbs, lipids, proteins, nucleic acids
Which of the four organic compounds are macromolecules?
Carbs, proteins, nucleic acids
Same molecular formula but different structural formula
Glucose, fructose, and galactose
Basic building block that can be a repeating unit
Two simple sugars bonded
What ratio must there be between hydrogen and oxygen in order for it to be a sugar
A molecule made of repeating units
Examples of polysaccharides
Where is starch stored?
Where is cellulose stored?
Cell wall of plants
Where is glycogen stored?
Where is chitin stored?
Exoskeleton of some animals
What do carbs provide?
Structure, quick energy when bonds break, protection
What do lipids provide?
Store energy, cushion, insulation, regulates what goes in and out of cell
What are phospholipids made up of? What is it?
Glycerol, phosphate group, two fatty acids . It's amphipathic
A molecule that has both hydrophobic and phyilic parts
Saturated vs. unsaturated fat
Sat is single bonded, can be compressed
Unsat is double bonded so it's bent
Bonds that bond sugar monosaccharides
Bonds that bond lipids
Ester bonds with long carbon chains
