Learning Goal 9.2 – 9.3.15 Students will understand that cell
respiration is the controlled release of energy from organic compounds to produce ATP, which in turn is used to provide energy for metabolic processes.
Topic 2.8Respiration
Breathe In . . . Breathe Out . . . How is breathing related to the process
of cellular respiration? You will receive a petri dish
Observe the dish Hold it close to your mouth and breathe on
it What do you observe?
Breathe In . . . Breathe Out . . . How is breathing related to the process of
cellular respiration? You will receive a bottle of water with
Bromthymol Blue indicator mixed with it. DO NOT DRINK THE LIQUID!!!!! Observe the color of the liquid Take a straw, put it in the bottle and blow GENTLY Blow for several minutes, observing color changes
as they occur Put the cap on the bottle and shake it. Observe the color
What is Respiration? Cellular respiration
is the process by which the chemical energy stored in the bonds of organic molecules is released and partially captured in the form of ATP.
Overview of Aerobic Respiration Reactants:
Oxygen Organic compounds
Carbohydrates Proteins Lipids
Products: ATP Carbon Dioxide Water
Respiration Respiration can
occur in the presence or absence of oxygen.
Respiration that occurs in the presence of oxygen is called aerobic respiration.
Aerobic Respiration Overview
A catabolic process – molecule is broken down, energy is released.
2 ATP molecules needed to start the process
4 ATP molecules are produced, but there were two to begin with, so the net gain is 2 ATP molecules.
6 carbons
3 carbons
Energy Coupling
Substrate Level Phosphorylation
Linking Reaction
Also known as the Kreb cycle.Occurs twice for each glucose molecule.
2 more ATP
32 – 34 ATP
Oxygen is required!
Aerobic Respiration Reactants: Products:
Aerobic Respiration Overview:
Overall Equation: C6H12O + 6 O2 6CO2 + 6 H2O
Reactants: Sugar (glucose) Oxygen
Products: Carbon dioxide Water
