|
Cells need energy for what?
|
Cell functions, transport of chemicals, movement
|
|
|
Name an energy molecule
|
ATP
|
|
|
ATP stands for
|
adenosine triphosphate
|
|
|
When ATP loses 1 phosphate it becomes
|
ADP--adenosine diphosphate
|
|
|
Where is energy stored in the ATP molecule?
|
the bonds between the phosphates
|
|
|
Photosynthesis
|
the process where light energy is converted to chemical energy
|
|
|
Chloroplast
|
The organelle where photosynthesis occurs,, contains chlorophyll
|
|
|
What are the two phases or stages of photosynthesis?
|
Light-independent
Light-dependent |
|
|
Light-Independent reactions
|
occur at night or in very low (little) light, makes sugars for the organism
|
|
|
Light-dependent reactions
|
Occur when there is light, these energy molecules are stored for use during light-independent times
|
|
|
6CO2 + 6H2O= C6H12O6 + 6O2
is the equation for what? |
PHOTOSYNTHESIS
|
|
|
The process by which mitochondria break down food molecules to produce ATP
|
Cellular Respiration
|
|
|
Name the 3 steps of cellular respiration
|
Glycolysis, Citric Acid Cycle, Electron Transport Chain
|
|
|
Anaerobic
|
no oxygen required
|
|
|
Aerobic
|
Oxygen is required
|
|
|
A series of chemical reactions in the cytoplasm of a cell that break down glucose resulting in 2 ATP
|
Glycolysis
|
|
|
Lactic Acid Fermentation
|
produces 2 ATP, supplies energy when little oxygen is avaliable, Exercise!
|
|
|
Alcoholic Fermentation
|
When yeast cells and some bacteria are used to produce carbon dioxide and ethyl alcohol (BREADS)
|
|
|
The process of cellular respiration produces energy and
|
CO2 carbon dioxide
|
|
|
During glycolysis sugar is broken down for energy. This is ineffective for energy production why?

Photolysis replaces electrons lost at the beginning of photosynthesis by spliting molecules of _____
|
H2O
|
|
|
