Antworten
-
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
Frage 2
Frage
During Respiration, what happens?
Antworten
-
Cells break down simple food molecules
-
Release the energy they contain
-
When it holds in all of the energy it has ever brought in
Frage 3
Frage
Energy stored in cells is something like money you take from a savings account from a bank.
Frage 4
Frage
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 ____ .
Frage 5

When cells need energy, they withdraw it by
Frage 6
Frage
The term respiration has two meanings.
Frage 7
Frage
What are the two stages of Respiration?
Antworten
-
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
Frage 8
Frage
Why is the Mitochondria often called the Powerhouses of the Cell?
Antworten
-
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
Frage 9
Frage
Oxygen is used in the SECOND stage of Respiration
Frage 10
Frage
In the FIRST stage of Respiration, Oxygen is not involved, and only a small amount of energy is released.
Frage 11
Frage
Two other products of Respiration are Carbon Dioxide and Water.
Frage 12
Frage
The CO2 and H20 diffuse out of the cell.
Frage 13
Frage
In most animals, the CO2 and some water leave the body during exhalation.
Frage 14
Frage
When you breath out, you release Oxygen. And when you breathe in, you breathe in Carbon Dioxide.
Frage 15
Frage
The Raw Material for Respiration are sugar and Oxygen.

Frage 17
Frage
Photosynsethis and Respiration cannot be thought of opposite processes.
Frage 18
Frage

Frage 19
Frage
What is Fermentation?
Antworten
-
An energy releasing process that does require oxygen.
-
An energy releasing process that does not require oxygen.
-
When cells obtain energy from glucose.
Frage 20
Frage
Fermentation provides energy for cells without using Oxygen.
Frage 21
Frage
The amount of energy released during Fermentation is much higher than the amount released during Respiration.

What are the products of A.F.?
Antworten
-
CO2 and a small amount of energy
-
H2O and a large amount of energy
-
H2O and a small amount of energy
Frage 25
Frage
Why does L.A.F. occur?
Antworten
-
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
