Basic Chem
Which type of bond, between a metal and nonmetal, involves electron donation/acceptance rather than sharing?
Ionic bond
Which molecule class includes monomers such as glucose, fructose, and galactose?
Carbohydrates
What determines whether a fatty acid is unsaturated or saturated?
Double bonds between carbons
Which weak bond bonds water molecules together?
Hydrogen Bond
Which molecule class consists of monomers built from a pentose sugar attached to a phosphate group and a nitrogenous base?
Nucleic acids
What resists changes in pH (i. e. modifies the pH to maintain a set point) in biological fluids?
Buffer
What bond includes two nonmetal atoms that are equally electronegative?
Nonpolar Covalent bond
Proteins
Considering that we can't get glucose/ATP from cellulose, why is it still an important part of the human diet?
Fiber for gut health
What is the octet rule? How many elements do not follow it?
Nearly all atoms require 8 electrons in their outermost shell, either in bonds or lone pairs. Hydrogen and helium only require two, as they have not filled the first (p) orbital of 2 electrons yet and moved on to 8 electron orbitals
Which molecule class is hydrophobic?
Lipids
What reaction forms monomers into polymers by removing water?
Dehydration synthesis
What is the difference between adhesion and cohesion?
Cohesion-water is attracted to/sticks to water
Adhesion- what is attracted to/sticks to other substances
Name the four levels of protein structure.
Primary, Secondary, Tertiary, Quaternary
What substance allows lipids and water to suspend into one another?
Emulsifier
