Objective: 1) Provide an example of an autotroph and a
heterotroph. 2) Illustrate how ATP is formed and broken down.

Defining Photosynthesis:
CO2 + H2O + sunlight Glucose and O2
Autotrophs
Autotrophs: Organisms that use photosynthesis (or
inorganic substances) to make organic substances (food).
Examples of Autotrophs:
#1 Plants
#2 Some bacteria and protists.
#3 Some autotrophs, such as bacteria found along the
bottom of the ocean, use chemical energy from
inorganic chemicals to make organic compounds.

Heterotrophs
Cellular respiration is almost the opposite of
photosynthesis.
Defining Cellular Respiration:
Glucose and O2 CO2 + H2O + ATP
Heterotrophs: Organisms that get their energy by
consuming other organisms.
Example:
1) You
2) All animals
KEY CONCEPT
Glucose (from photosynthesis) ATP (from cellular
respiration)
1. ATP is the fuel of the cell. It is made
from Glucose which is refined by cellular
respiration.
2. Energy is Stored when a phosphate group
is added to ADP to make ATP.
3. Energy is Released when ATP is split to
make ADP and a phosphate group
2
ATP Synthase: an
enzyme in mitochondria
and chloroplasts that
makes ATP. H+ makes it
work.
