Chapter 1 - 3 Quiz 1 Review Flashcards
What is Homeostasis?
- Maintenance of a relatively stable internal environment
o Environmental factors that affect cell
o Materials needed for cells needs
o Factors cells use to communicate with each other
What is the ionic distribution between outside of a cell and inside of a cell?
- Ions have a concentration gradient across membrane. ie: potassium K+ is higher inside and a low concentration outside the membrane
Monounsaturated Fat
Fatty acids with one double bond (Oleic acid)
Polyunsaturated Fat
Fatty acids with two or more double bond (Linoleic acid)
Monosaccharide
Simple sugars
Ribose, Deoxyribose, Fructose, Glucose, Galactose
Disaccharides
Glucose + another monosaccharide
Polysaccharide
Glucose polymers
Primary Structure of a Protein
the sequence of the amino acid strings
Secondary structure
the covalent bond angles and hoops of the amino acid

Covalent Bonds
A bond between atoms when electrons are shared – requiring energy to make or break
What are the two types of covalent bonds?
a. Non-polar – even distribution of electrons
b. Polar – Regions of partial charge. (ie: water)
What is an Ionic Bond?
Electrostatic attraction where opposite charges attract. Atoms lose or gain electrons
Hydrogen Bond
Weak bond that require little energy to break
ie: water surface tension slide
Van der Waals Force
Weak and non-specific attractions (bond) between atoms
