animal and plant metabolism• Answer• Mitochondria, chloroplast

Organelles : 800

• Question:• Animal metabolism (cellular respiration)

happens in 3 stages: Glycolysis, Citric Acid Cycle, and the Electron Transport Chain. Which of these 3 stages takes place outside the mitochondria?

• Answer:• glycolysis

Organelles : 1000• Question:

• Describe the organelles involved in protein synthesis and their role in the process from start to finish.

• Answer• Nucleus (store DNA), Ribosome (translate mRNA),

Golgi (protein modification)

Transport: 200• Question:• Molecules diffusing across a membrane from

high concentration to low concentration is what type of transport?

• Answer• Passive Transport

Transport : 400• Question:• Molecules being moved across a membrane

from low concentration to high concentration is what type of transport? What does this type of transport require?

• Answer• Active transport, energy

Transport : 600• Question:• Simple diffusion directly across a membrane is

possible with small molecules. What type of diffusion happens when larger molecules need the help of a transport protein?

• Answer• Facilitated diffusion

Transport : 800• Question:• A slice of potato is placed in a glass of highly

concentrated salt water. Will the potato shrink or swell, and why?

• Answer• Shrink- water moves to the higher

concentrated salt water

Transport : 1000• Question:

• A slice of potato is placed in a glass of water with a solute concentration equal to that of the potato. Will the potato shrink or swell, and why?

• Answer• Neither- equal concentration of solute so no

osmosis.
