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.
4 PRIMARY TYPES OF TISSUES • Epithelial • Connective • Muscle • 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 cells Squamous– 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 tissues Functions: Binds body tissues together, Supportsthe body, Provides protection
Dense Connective Tissue Dense 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 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
Nervous Tissue Called neurons Cytoplasm drawn out into long extensions ( 3 feet or more in the leg!)
