What is the "formula" for photosynthesis?
|
Carbon dioxide+water+sunlight=oxygen and sugar
|
|
|
What are elements made up of?
|
Atoms
|
|
|
What can proteins be used for?
|
To speed up chemical reactions just like an enzyme
|
|
|
What are DNA's and RNA's?
|
Nucleic acids
|
|
|
What is diffusion
|
When molecules move through a cell membrane. This is where the molecules move from a higher concentration to a lowere one.
|
|
|
What is osmosis?
|
When water molecules move through a membrane from a higher concentration to a lower one.
|
|
|
What is passive transport?
|
When the molecules move from the higher concentration to the lower concentration without making the cell use its own energy
|
|
|
What is active transport?
|
When molecules move from the lower concentration to a higher one and makes a cell use its own energy.
|
|
|
What is stage 1 of photosynthesis?
|
Stage 1: Captures the sun's energy
|
|
|
What is stage 2 of photosynthesis?
|
Stage 2: Uses the sun's energy to make food.
|
|
|
What is one example of a carbohydrate?
|
Starch
|
|
|
What is the organelle in which photosynthesis occurs?
|
The chloroplast
|
|
|
What produces carbon dioxide?
|
Respiration
|
|
|
During respiration where is the most energy released?
|
Mitochondria
|
|
|
What is an energy releasing process that does not require oxygen?
|
Fermentation
|
|
|
What would happen to the chemical reactions in a living thing if there were no enzymes?
|
The reactions would either be extremely slow or wouldn't happen at all.
|
|
|
Why do organisms carry out the process of respiration?
|
Cells need energy to operate and for an organism to get energy it needs cellular respiration.
|
|
|
How does photosynthesis help respirations in plants?
|
Photosynthesis produces the sugar (glucose) that cells have to break down during respiration (for autorotrophs).
