BIO 151- Module 1
1.ATP: energy rich molecule that powers cellular activities
2.Creation of ATP / Cellular respiration: •Glycolysis, Citric Acid Cycle (Kreb's Cycle), Electron transport chain.
•Provides cells with the energy they need to function from breaking down sugar.
•Cellular respiration + Oxygen = ATP
3.Glycolysis: Break down glucose (with 6 C atoms) into 2 pyruvic acid molecules to create 2 ATP molecules
(C6--> 2P + 2ATP)
4.Citric Acid Cycle: Body breaks down pyruvic acid to make 2 more ATP and release electrons (P---> 2 ATP)
5.Electron Transport Chain: •Body uses electrons to produce most of it's ATP.
•All high energy electrons from glycolysis and CAC are used.
•Electrons interact with enzymes that store energy in the electrons
in ATP mole- cules. (+36-38 ATP)
6.Catabolism: Break down of substances into simpler building blocks
7.Anabolism: •Synthesize more complex structures from simpler ones
•Used to make ATP
8.Metabolism: Chemical reactions in the body that allow us to function
9.Anatomy: Structure of the body and design
10.Physiology: •How the body functions
•Depends on bone structure
11.8 levels of organization: 1. Atom
2.Molecule
3.Macromolecule
4.Organelle
5.Cell
6.Tissue
7.Organ System
8.Organism
12.6 levels of the human body: chemical, cellular, tissue, organ, organ system, organism .4 Tissue types: 1. epithelial
2.connective .muscle
4.nervous
•Make up organ structure
14.epithelial tissue: •covers body surfaces and lines body cavities
•Secrete and absorb materials
•Constant cell division to replace dead cells
•Closely packed cells with little matrix
•Can be +1 layers
15.Muscle tissue: • Allows movement
•Cells are specialized for muscle contraction
16.Connective tissue: • Support and protect body organs (bones, tendons, blood ligaments)
•Cells bind tissue together and are supportive
17.Nervous tissue: • Communicates between cells of body by sending electrical impulses that communicate rapidly
•"wiring" of body
18.12 Organs systems: 1. Integumentary / Skin
2.Skeletal
