CHAPTER 2 - LIFE & ENERGY

Labs: Corn seed lab & calorimeter lab (calorimeter lab not done 2007)

Understand how these labs connect to the chapter and what major points they illustrate!

abiotic

Activation energy (for this course: same as free energy),

Active site

Autotroph/producer

Bioaccumulation

Biomagnification

biosphere

biotic

Calorie/Kilocalorie

cellular respiration

chemical energy

Chemoautotroph

Chemosynthesis

ecosystem

entropy

Enzyme

Food chain

Food web

free energy (for this course: same as activation energy), heat energy

heterotroph (consumers and decomposers)

hydrothermal vents

metabolism (anabolic/catabolic)

peristalsis

Photoautotroph

photosynthesis

Salivary amylase

Substrate

Trophic levels

Major concepts-

· Characteristics of living organisms/indicators of “being alive”

· Two laws of thermodynamics

· Components of an ecosystem [energy source, producer, consumer] (primary/first order…), decomposer] & food webs

· Food chain compared to a food web

· Conversions of energy from one form to another (solar E -> chemical E -> free E -> heat E)

· 10% rule of trophic levels

· ATP & ADP (functions, general structures, and concept of how it is rebuilt using food energy during cellular respiration)

· Biotic contrasted to abiotic

· Enzymes and how they work

· induced fit

· lock and key

· Parts of the digestive system
