Energy and the Cell

1. Matter and EnergyHow they interact with each other and the

environmentHow they move through the environment

2. Systems Basic Structure and how to apply to biological

concepts3. Structure & Function

How does the structure aid in the function?4. Change Over Time5. Behavior & Interactions

To understand Science you have to understand a few key themes

Formulas Must Be Memorized!!!!!

Photosynthesis:CO2 + H2O + Energy C6H12O6 + O2

Cellular Respiration:C6H12O6 + O2 CO2 + H2O + Energy

Matter and Energy you need to know for this unit

Cellular Respiration

Where: Occurs in all cells (including plants and animals)

Structure: Specifically in mitochondria

Function: Converting Glucose into Energy

Chemical Formula:C6H12O6 + O2 CO2 + H2O + Energy

Cellular Respiration

Memorize

Aerobic means: “with oxygen”Oxygen is always need to ignite somethingRespiration is similar to burning a

marshmallow

Anaerobic means: “without oxygen”If not oxygen is present, respiration still

happens, but it is not as efficient (producing less energy).

Aerobic Respiration

1. What is the source of carbon for cellular respiration?Glucose (C6H12O6) is the carbon source.

2. Where do Stages 2 and 3 of cellular respiration take place?in mitochondria

Mitochondria Videos

GlycolysisLocation:

Cytoplasm outside of the mitochondria

2 ATPs to get reaction going

Gross total = 4 ATPs generated

Net total = 2 ATPs

Krebs CycleModern name is the

“Citrus Acid Cycle”Location: inside

mitochondria Net total = 2 ATPs
