Do Now: How do you get your energy? Homework: pg #85 # 1-5 ****EXAM TUESDAY!!!! (Cell transport and cell processes, microscope)*****

Production of ENERGY (ATP) Need nutrients (glucose) to make energy needed perform various activities

Aerobic Respiration Anaerobic Respiration Where does cellular respiration happen??

Do Now: Describe the process of aerobic respiration. Where does it occur? Homework: Enjoy your weekend!!!! ****EXAM TUESDAY!!!! (Cell transport and cell processes, microscope)*****

Aerobic Respiration Oxygen is used to produce ATP Occurs in mitochondria C 6 H 12 O 6 + O 2  CO 2 + H 2 O + 36ATP energy

Glucose + Energy Oxygen Carbon Dioxide Water + +

Anaerobic Respiration Oxygen is NOT used to make energy Only 2 ATP produced Fermentation 2 Types:

1. Alcohol Fermentation Occurs in yeast and bacteria Important to the brewing and baking industries C 6 H 12 O 6  ethyl alcohol + CO ATP

2. Lactic Acid Fermentation Occurs in animals (muscle cells) Can lead to muscle fatigue C 6 H 12 O 6  lactic acid + 2 ATP

Summary Aerobic Respiration Glucose + Oxygen  Carbon Dioxide + Water + 36 ATP C 6 H 12 O 6 + O 2  CO 2 + H ATP

Anaerobic Respiration Ethyl Alcohol Fermentation Glucose  Ethyl Alcohol + CO ATP Lactic Acid Fermentation Glucose  Lactic Acid + 2 ATP

What is photosynthesis? Process in which plants use sunlight (energy) to produce glucose (food) Process in which plants use sunlight (energy) to produce glucose (food) Form of autotrophic nutrition – the ability to make food Form of autotrophic nutrition – the ability to make food Occurs in chloroplasts Occurs in chloroplasts

What is the equation for photosynthesis? 6 CO H 2 O → C 6 H 12 O O 2 Raw materials Products sunlight chlorophyll GLUCOSE Waste – Into air
