College Biology Chapters 1-5

QuestionAnswer
How do you calculate neutrons Mass # - Atomic #
What is inside the nucleus ? What is on the outside? Pro and Neu are inside. Electrons are on the outside.
What is an Isotope? Element that has a different # of neutrons
what is an Ion charged element (gain or loss of electrons)
What is an Ionic Bond? Loss of electrons by an element/atom and a gain by an atom/element
What is an element A chemical element is a substance that cannot be broken down by chemical means
what is an inorganic compound? usually contains carbon and hydrogen
what is an organic compound? Carbon compounds
4 kingdoms that make up the domain eukarya Protista (Multiple Kingdoms) Animalia Fungi Plantae
What is a compound A substance formed by the reaction of two or more chemical elements
What is an atom smallest component of an element having the chemical properties
solvent, solute, and solution solvent is a substance which dissolves a solute. When a solvent dissolves into a solute, it creates a solution.
Why is hydrogen bonding (interaction) important Thier presence explains many of the properties of water. They are used to stabilize and determine the structure of large macormolecules like proteins and nucleic acids.
What is organic chemistry? The study of organic compounds
what is an Enantiomer Each of a pair of molecules that are mirror images of each other.
functional groups hydroxyl, amino, and carbonyl Hydroxyl groups - this is a two atom group with symbol -OH. A carbon atom is joined to the O atom and the hydrogen atom is significantly positive and is easily lost to form the RO- ion.
monomer and polymer A monomer is a molecule that is able to bond in long chains
4 levels of protein structure Primary: order of the amino acids. Secondary: localized modular structure. Tertiary Structure: 3D shape of the protein Quaternery: the association of more than one peptide bond.
Definition of denature To induce structural alterations that disrupt the biological activity of a molecule.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
