Biology Review for Anatomy and
Physiology
Atom• Smallest part of an element• Ca, Mg, Na
Molecule• Two or more atoms bonded together• NaOH, HOH
Organelle• Parts that make up cells• mitochondria
Cell• Makes up all living matter• Blood cell, nerve cell, muscle cell
Tissue• Makes up organs of the body• Skin, muscle, bone, brain
organ• Structure made up of tissues with specialized
function• Stomach, liver, brain
Organ system • Group of organs specialized for certain functions• Digestion, respiration
Organism• An individual living thing
Population• A group of organisms• Jasper Florida

What does organic mean to you?
Organic Inorganic
I). Organic compounds
Contain carbon
covalently bonded
binds with hydrogen
units bind together
Why is water so important to the human body?
Why are salts so important?
CarbohydratesGlucosestarch
LipidsFatty acids
Saturated fats
Amino AcidsAmino Acids
Peptides and proteins
Nucleic AcidsNucleic AcidsDNA & RNA
Types of organic molecules
Enzymes are protein molecules that are manufactured by all plant and animal cells. All cells require enzymes to survive and function. Enzymes are catalysts, which means that they make chemical reactions go faster, but are not changed by the reaction.
Enzymes are composed primarily of proteins, which are polymers of amino acids.
What is protein denaturation?
Adenosine triphosphate
• Controls cell activities• Contains the hereditary material of the cellNucleus
• Synthesize protienRibosomes
• Support and protection• Controls movement of materials in/out of cell• Barrier between cell and its environment• Maintains homeostasis
Cell membrane
Cytoplasm (Cytosol)• Supports and protects cell
organellesMitochondria• Breaks down glucose molecules to
release energy• Site of aerobic cellular respiration
endoplasmic reticulum• Carries material through cell• Aids in making proteins
Golgi apparatus• Have a cis & trans face• Modify proteins made by the cells• Package & export proteins
• Breaks down larger food molecules into smaller molecules
• Digests old cell partsLysosomes
• Strengthen cell & maintains the shape
• Moves organelles within the cellCytoskeleton
• Where cell microtubules get organized
• Regulate the cell division cycle
Centrosome/Centrioles
Purpose of membrane proteins
Relay signals between the cell’s internal and external
environments
Move molecules and ions
across the membrane
Allow cells to identify each other. AKA –
immune response
Moving material in the direction of the
concentration gradient
No energy needed
Can move materials any direction regardless of
concentration gradient
Need energy to function
Examples: Pinocytosis
Phagocytosis receptor mediated
Energy is required
Example: secretion of certain hormones
There is also transcytosis.
Prophase MetaphaseAnaphase TelophaseG1 phase: cell growthS phase replicating genetic material
What is a gene?
