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
