1Located in the atom are: [blank_start]protons[blank_end] that have a positive charge, neutrons that have [blank_start]no[blank_end] charge, and electrons that have a [blank_start]negative[blank_end] charge
- Aprotons
- Bno
- Cnegative
2When an atom loses an electron it becomes more [blank_start]positive[blank_end] and becomes a [blank_start]cation[blank_end]
- Apositive
- Bcation
3When an atom gains an electron it becomes more [blank_start]negative[blank_end] and becomes an [blank_start]anion[blank_end]
- Anegative
- Banion
4The atomic number is relative to the number of [blank_start]protons[blank_end] the atom has
- Aprotons
5Covalent bonds are bonds where electrons on the outmost ring are [blank_start]shared[blank_end]. A covalent bond is generally known as a [blank_start]strong[blank_end] bond.
- Ashared
- Bstrong
6Two types of covalent bonds are [blank_start]polar[blank_end] and [blank_start]nonpolar[blank_end]
- Apolar
- Bnonpolar
7Nonpolar is the [blank_start]equal[blank_end] sharing of electrons between 2 atoms
- Aequal
8Polar bonds are [blank_start]unequal[blank_end] sharing of electrons, this causes small regional [blank_start]negative[blank_end] and [blank_start]positive[blank_end] poles
- Aunequal
- Bnegative
- Cpositive
9[blank_start]Ionic bonds[blank_end] are the complete donation of an electron(s) to another atom
- AIonic bonds
10[blank_start]Hydrogen[blank_end] bonds are [blank_start]weak[blank_end] charges on polar water molecules attracted to other negative or positively charged atoms or molecules
- AHydrogen
- Bweak
11Van der Waals forces is the weak attractive force between 2 [blank_start]polar molecules[blank_end] or a [blank_start]polar[blank_end] molecule and an [blank_start]ion[blank_end]
- Apolar molecules
- Bpolar
- Cion
12[blank_start]Solute[blank_end] is a substance dissolved in liquid
- ASolute
13A [blank_start]solvent[blank_end] is the liquid that the solute is dissoveled into
- Asolvent
14A [blank_start]solution[blank_end] is the solute dissolved in the solvent
- Asolution
15[blank_start]Hydrophilic[blank_end] is a water-loving molecule
- AHydrophilic
16[blank_start]Hydrophobic[blank_end]: water-fearing molecules
- AHydrophobic
17[blank_start]Amphipathic[blank_end]: molecules that are part hydrophobic and part hydrophilic, having both polar and nonpolar portions
- AAmphipathic
18[blank_start]Molarity[blank_end] is the amount of solute in a unit volume solution
- AMolarity
19[blank_start]Acid[blank_end]: adds H+to solution (H+donor)
- AAcid
20Base: [blank_start]decreases[blank_end] number of H+ in solution (H+acceptor)
- Adecreases
21The higher the [H+], the [blank_start]lower[blank_end] the pH
- Alower
22The lower the [H+], the [blank_start]higher[blank_end] the pH
- Ahigher
23Anything [blank_start]greater[blank_end] than a pH of 7 is said to be basic or alkaline. Anything below 7 is said to be [blank_start]acidic[blank_end]
- Agreater
- Bacidic
24ECF normal range for pH is [blank_start]7.35[blank_end] to [blank_start]7.45[blank_end]
- A7.35
- B7.45
25[blank_start]Carbohydrates[blank_end] are long chains of sugar and are made of [blank_start]oxygen[blank_end], [blank_start]hydrogen[blank_end] and [blank_start]carbon[blank_end]. They are the most abundant.
- ACarbohydrates
- Boxygen
- Chydrogen
- Dcarbon
26Lipids are the most diverse and are [blank_start]nonpolar[blank_end] so they are hydrophobic. made up of [blank_start]fatty-acid[blank_end] chains that have a [blank_start]glycerol[blank_end] head and a number of fatty-acid tails.
- Anonpolar
- Bfatty-acid
- Cglycerol
27Saturated fats contain [blank_start]no[blank_end] double bonds and is [blank_start]solid[blank_end] at room tempurature
- Ano
- Bsolid
28[blank_start]Unsaturated[blank_end] fats contain a double bond and are liquid at room temperature
- AUnsaturated
29[blank_start]Proteins[blank_end] are the most versatile molecule. They are made of 20 different [blank_start]amino acids[blank_end] and millions of different combinations
- Aamino acids
- BProteins
30Proteins are made of [blank_start]amino acids[blank_end] that are composed of a [blank_start]carboxyl[blank_end] group, an amino group, a [blank_start]hydrogen[blank_end] and a R group
- Aamino acids
- Bcarboxyl
- Chydrogen
31[blank_start]Proteins[blank_end] can have 4 different structures, primary, secondary, tertiary and Quaternary.
- AProteins
32Amino acids combine together to form [blank_start]peptide[blank_end] bonds
- Apeptide
33Nucleotides are made of a base [blank_start]sugar[blank_end] and a [blank_start]phosphate[blank_end]
- Asugar
- Bphosphate
34Single [blank_start]nucleotides[blank_end] are used primarly to capture and transfer energy
