Proton / positive charge / plus sign Atomic Structure Nucleus: protons: p+ neutrons: n0 Energy Levels: electrons: e- orbitals Neutron / neutral charge/ no sign Electron / negative charge / minus sign 19
20
Atomic Level: Atoms are elements with specific properties
Ex: C, H, O, N
21
Molecular Level: Molecules are combinations of atoms
Ex: Actin
22
Organelle Level: Organelles are made up of different molecules
Myosin Ex: Sarcomere
23
Cellular Level: Cells are composed of various organelles
Ex: Cardiocyte
24
Tissue Level: Tissues are composed of several cell types
25
Organ Level: Organs are composed of various tissue types
(Ch 5-19)
26
Organ System Level: Organ systems are composed of various organs
(Ch 5-12) (Ch 13-19)
27
Organism Level: Organisms are composed of several organ systems
I sure hope this dude is planning on taking a break soon!!

57
Learning Objectives Explain the concept of homeostasis and its significance to living things Describe how positive and negative feedback are involved in homeostatic regulation
58
Homeostasis The steady-state physiological condition of a body
The automatic tendency to maintain constant internal conditions despite changes in the external environment Maintained by feedback mechanisms – especially feedback inhibition 58
59
Homeostasis: A Regulatory Process

62
Regulatory Mechanisms
Negative feedback Feedback inhibition: increasing amounts of an end product in a chemical synthesis pathway causes the reaction to slow down or stop Positive feedback Increasing amounts of an end product in a chemical synthesis pathway causes the reaction to speed up 62
63
Negative Feedback An anabolic biosynthetic pathway produces a chemical product. The product interacts negatively with a catalytic enzyme in the pathway. As more product is produced, synthesis of product is reduced. Note: less product = more production of product. More product = less production of product. 63
64
Positive Feedback An anabolic biosynthetic pathway produces a chemical product. The product interacts positively with a catalytic enzyme in the pathway. As more product is produced, synthesis of product is increased. Note: less product = less production of product. More product = more production of product. 64
