 Practice Objectives
Calorie lab
questions
Objective 19

activities that break down
molecules
Anabolic—chemical
activities that build
molecules.
Objective 20
Cell
Respiration—
process by which food
substances are broken
down to release bond
energy to form ATP
Obj. 20 cont.
Major
Steps
–1. Glycolysis
–2. Citric Acid Cycle

oxidative
phosphorylation
Objective 21
Energy
Balance (from
food oxidation) is
precisely balanced by
energy output (heat,
work, storage)
Objective 22

Basal Metabolic Rate (BMR)

expended (heat produced) by
body per time unit under
controlled conditions.
 Energy needed to perform
basic activities
Objective 22 Cont.

metabolic rate
total rate of kilocalorie
consumption to fuel all
ongoing activities--voluntary & involuntary
(bulk of TMR is BMR)

action of foods
Obj. 24 Temperature
Regulation
Body
temperature is the
balance between heat
production and heat loss.
