Aim: How do living things accomplish anaerobic respiration?

What do all living things do to acquire energy? To get

Breathing The processes of taking in oxygen and releasing carbon dioxide with the use of the respiratory tract. Cellular Respiration The process by which organisms break down organic molecules (glucose) to release energy(ATP).

What is Anaerobic Respiration? ENERGY Organisms make ATP (energy) without oxygen This process is also called fermentation There two types of anaerobic respiration:

Alcoholic Fermentation Glucose  2 CO2 + 2 Ethyl Alcohol What is the name of the process that converts glucose into pyruvic acid? Glycolysis What is the net gain in ATP for this process? 2 ATP

Besides alcohol what else is a waste product of alcoholic fermentation? Yeast is a unicellular organism capable of carrying out alcoholic fermentation

Bakers Yeast The CO2 that is released during fermentation creates bubbles and pockets that make bread rise.

Can we do anaerobic cell respiration? Yes, when our muscles run out of oxygen they do lactic acid fermentation

Lactic Acid Fermentation Glucose  2 Pyruvic Acid  2 Lactic Acid What is the name of the process that converts glucose into pyruvic acid? Glycolysis What is the net gain in ATP for this process? 2 ATP

What does the lactic acid cause to happen to our muscles? MUSCLE FATIGUE!!! That equals PAIN!!!!!!!

Types of Anaerobic cell respiration Lactic acid fermentation Glucose 2 ATP + Lactic acid Alcohol fermentation Glucose 2 ATP + 2CO2 + Alcohol

Why do bread and Swiss cheese have so many holes?

Alcohol fermentation vs Lactic A. Fermentation What is the organic compound used by both? Glucose What is their main product? 2 ATP How are they different? Alcohol fermentation produces alcohol and lactic acid fermentation produces lactic acid What organisms utilize alcohol fermentation? Yeast and Bacteria What organisms utilize lactic acid fermentation? Bacteria & Animal muscle cells when they run out of oxygen
