How many years ago did the evolution of
complex multicellular organisms occur?
DEFINITION 2 600 MYACellular specialization at the expense of cellulfar autonomy TERM 3
Signal Transduction
DEFINITION 3 The process by which a cell converts an extracellular signal into a reponse. TERM 4
Hormone
DEFINITION 4 Information-carrying molecule that is secreted from a cell, circulates in the body, and acts on target cells far from the signaling cell. TERM 5
Endocrine System
DEFINITION 5 The body's system of glands that secrete hormones in order to regulate the body. Only certain cells respond.
TERM 6
Structure of Hormones. They are made of...
DEFINITION 6 Polypeptides, Amino Acids/Derivatives, and steroids. TERM 7
Cell Signaling Process (Outline)
DEFINITION 7
- Reception2. Transduction3. Response TERM 8
Transduction Steps
DEFINITION 8
- Molecules that relay a signal from receptor to response are mostly proteins2. One receptor activates another protein and so on until response occurs3. At each step the signal becomes a different form, usually "conformational"4. It can... amplify a signal, or provide more coordination and regulation TERM 9
Phosphorylation
DEFINITION 9 The addition of a phosphate to a protein or enzyme and can facilitate the start or stop of the reaction. TERM 10
Protein Kinases
DEFINITION 10 Enzymes that transfer phosphate from ATP to the hydroxyl R groups of serine, tyrosine, or threonine.
