1. Warm-Up
1.What is a enzyme? 2. What is a substrate? 3. What is the name of the place on the enzyme that the substrate attaches to? 4.True or False? Enzymes are destroyed after a reaction. 5. What are factors that can change an enzymes shape and alter an enzymes function. 6. Write down 3 examples of enzymes and state their function in the body.

2. Enzymes
In the surrounding circles, add information on the characteristics that describe enzymes. Write a brief summary in your own words explaining the characteristics above and include an illustration of a enzyme.

3. Types of Tissues

4. 4 PRIMARY TYPES OF TISSUES
Epithelial
Connective
Muscle
Nerve

5. Epithelial Tissues Found in Body coverings, linings, Glandular tissue
Functions: Protection, Absorption, Filtration, Secretion

6. Epithelium
-Number of cell layers Simple – one layer Stratified – more than one layer -Shape of cells Squamous – flattened Cuboidal – cube-shaped Columnar – column-like

7. Glandular Epithelium
-Gland – one or more cells that secretes a particular product -Two major gland types -Endocrine gland -Ductless -Secretions are hormones -Exocrine gland -Empty through ducts to the epithelial surface -Include sweat and oil glands

8. Connective Tissue
Found everywhere in the body and is the most abundant and widely distributed tissues Functions: Binds body tissues together, Supports the body, Provides protection

9. Dense Connective Tissue
Dense fibrous Tissue –Ligaments –Cartilage -Hyaline: Covers the ends of bones, most abundant cartilage -Fibro-cartilage –Elastic, vertebrae disks, ears, nose

10. Loose Connective Tissue
-Areolar Tissue: Most widely distributed, holds organs together, cushions &protects organs, reservoir for water and salts (edema) -Adipose tissue: Areas of stored fats (fat deposits)

11. Muscle Tissue
Skeletal Muscle: voluntary -contract – pull on muscle -Attached to bone -multinucleate -striated -striped
Smooth muscle:
involuntary
visceral
no striations
-uni-nucleate
-spindle shaped
-peristalsis(Stomach contraction)
Cardiac muscle: involuntary
-striated
-uninucleate
-heart only
-intercalated discs

12. Nervous Tissue
Called neurons Cytoplasm drawn out into long extensions ( 3 feet or more in the leg!)
