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.

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.

Types of Tissues

4 PRIMARY TYPES OF TISSUES

1. Epithelial 2. Connective 3. Muscle 4. Nerve

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

Epithelium-Number of cell layers

Simple – one layer Stratified – more than one layer

-Shape of cellsSquamous – flattened Cuboidal – cube-shaped Columnar – column-like

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

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

Dense Connective TissueDense fibrous Tissue –Ligaments –Cartilage

-Hyaline: Covers the ends of bones, most abundant cartilage -Fibro-cartilage –Elastic, vertebrae disks, ears, nose

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)

Muscle TissueSkeletal 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

Nervous Tissue

Called neurons Cytoplasm drawn out into long extensions ( 3

feet or more in the leg!)
