AP 100 Flashcards
Subatomic Particles
Protons, neutrons, electrons
Inorganic molecules
include water, oxygen gas, carbon dioxide gas
organic molecules
contain carbon atoms in chains or rings with hydrogen atoms attached
4 types of tissues in humans
Epithelial, connective, muscle, nervous
is the sum of all chemical processes occurring in the body. consists of anabolic/catabolic reactions
Metabolism
building of large, complex, organic molecules using energy (ATP)
Anabolic reaction
Breakdown of large, complex organic molecules into simpler organic molecules
Catabolic reaction
Ability to detect and respond to internal and external stimuli
Responsiveness
a process whereby a cell changes from an unspecialized cell to a specialized cell with specific functions
Differentiation (e.g stem cells)
outer cells which eventually form epidermis of skin and nervous tissue
ectoderm
middle cells which eventually form muscle, connective tissue
mesoderm
- inner cells which eventually form lining of digestive tract
endoderm
a cycle of events which involve continuously monitoring a controlled
condition
Feedback system (positive; enhances stimulus. negative; reverses stimulus)
subjective changes in body function that are not observable
Symptoms
changes that can be observed and measured
signs
