Comprised of different tissue types and preform different functions |
|
|
Organ system |
Organs and structures of a particular body system |
|
|
Organism |
All body systems together |
|
|
Bonding of atoms |
When atoms combine with other atoms that either gain or lose electrons or share electrons with other atoms |
|
|
Ionic bonds |
Are formed when one atom donates (loses) an electron to another atom (which gains the electron) |
|
|
Covalent bonds |
- Are formed when electrons are shared between atom. - covalent bonds are stronger than ionic bonds |
|
|
Polar covalent bonds |
Unequal |
|
|
Nonpolar covalent bonds |
Equal |
|
|
Acids |
Substances that release H+ in water |
|
|
Bases |
Substances that release OH- in water |
|
|
Homeostasis |
Maintenance of a relatively constant internal environment |
|
|
Inorganic molecules |
Most lack Carbon, lack C-H bonds, usually dissolve in water and typically are smaller than organic molecules |
|
|
Organic molecules |
Arise from living organisms, many C atoms, many C-H bonds |
|
|
Carbohydrates |
Canta in C, H, and O atoms comprised of monosaccharides Ex- glucose |
|
|
Disaccharide |
2 monosaccharides put together (lactose) |
|
|
Polysaccharides |
Many monosaccharides put together (glycogen) |
|
|
Steroids |
Interconnected rings of C atoms |
|
|
Proteins |
Contains C, H, O, N, and S atoms, comprised of amino acids (building blocks of proteins) |
|
|
Amino acids |
Contains an acid group and an amine group |
|
|
Nucleic acids |
Contain C, H, O, N, and P atoms, comprised of nucleotides |
|
|
Nucleotide |
Contains of 5C sugar + a phosphate group + a nitrogenous base Ex- DNA |
|
|
Plasma membrane ( fluid mosaic model) |
Defines the cell and controls the exit and entrance of materials Features- semi-permeable( selectively permeable) and dynamic ( always changing) |
|
|
Cholesterol molecules |
Consist of for fused rings of carbon atoms, provide stability for the plasma membrane |
|
|
Glycocalyx |
- Branching carbohydrate groups that help adjacent cells adhere to one another and can act as cell markers. - The carbohydrate group can either be attached to a phospholipid or a protein. |
|
|
Proteins |
- Can be involved in structural support and transport. - Proteins was in the plasma membrane can also function as receptors, enzymes and/ or some markers. |
