What is Respiration?
An energy-releasing process that does not require oxygen
The process by which a cell captures energy in sunlight and uses it to make food
The Process by which cells obtain energy from glucose
During Respiration, what happens?
Cells break down simple food molecules
Release the energy they contain
When it holds in all of the energy it has ever brought in
Energy stored in cells is something like money you take from a savings account from a bank.
During photosynthesis, plants capture the energy from sulight and save it in the form of carbohydrates, including sugars and starches. Similarly when you eat a meal you ____ .
Add to your body's energy savings account
Take away from your body's energy savings account
When cells need energy, they withdraw it by
Breaking down the carbohydrates
A- and using the process of respiration
Both A & B
The term respiration has two meanings.
Cellular Respiration & Air moving in and out of your lungs
Cellular Respiration & Fermentation
What are the two stages of Respiration?
1- In the Cytoplasm ; The molecules of glucose are broken down into smaller molecules 2 - In the Mitochondria ; Small Molecules are broken down into even smaller molecules
1- In the Fermentation ; the Cytoplasm breaks down the muscles 2- The Respiration in the Mitochondria
Why is the Mitochondria often called the Powerhouses of the Cell?
It makes the small molecules beak down into even smaller molecules
When chemical reactions require oxygen and release a great deal of energy
The molecules of glucose are broken down into smaller molecules
Oxygen is used in the SECOND stage of Respiration
In the FIRST stage of Respiration, Oxygen is not involved, and only a small amount of energy is released.
Two other products of Respiration are Carbon Dioxide and Water.
The CO2 and H20 diffuse out of the cell.
In most animals, the CO2 and some water leave the body during exhalation.
When you breath out, you release Oxygen. And when you breathe in, you breathe in Carbon Dioxide.
The Raw Material for Respiration are sugar and Oxygen.
During Respiratoin what 2 items are used to produce Sugar and Oxygen
Sugars & Carbon Dioxide
Water & Sugar Glucose
Carbon Dioxide & Water
Photosynsethis and Respiration cannot be thought of opposite processes.
Single-Celled Organisms Obtain their energy through Respiration
What is Fermentation?
An energy releasing process that does require oxygen.
An energy releasing process that does not require oxygen.
When cells obtain energy from glucose.
Fermentation provides energy for cells without using Oxygen.
The amount of energy released during Fermentation is much higher than the amount released during Respiration.
What are two types of Fermentation?
Alcoholic & Drug Fermentation
Alcoholic & Yeast Fermentation
Energy Fermentation
Lactic Acid & Alcoholic Fermentation
What makes Alcoholic Fermentation occur?
When Yeast and some other single-celled organisms break down sugars.
When you get a cramp because you have been drinking too much alcohol.
What are the products of A.F.?
CO2 and a small amount of energy
H2O and a large amount of energy
H2O and a small amount of energy
Why does L.A.F. occur?
Because your cells are obtaining too much oxygen than they can handle.
Because your cells are not receiving the proper amount of carbon dioxide.
Because your cells are not obtaining enough oxygen for your cells
Because your cells are taking in more oxygen than they can replace
L.A.F. Supplies your cells with energy
