Question

1. which means of particle transport requires input of energy from the cell? a diffusion b osmosis c facilitated diffusion d active transport 29. what type of cell transport is being shown in the following diagram? a endocytosis b diffusion c exocytosis d osmosis 30. this is the process in which molecules that are too large to pass through the lipid bilayer pass through protein channels a passive transport b osmosis c facilitated diffusion d active transport 31. an egg was placed in a mysterious solution. after 24hrs you observed the egg has appeared to have shrunk and looks shriveled up. what kind of solution was it most likely? a water b hypertonic c isotonic d hypotonic 32. what type of solution is the following cell in? a hypertonic b hypotonic c isotonic 33. which of the following organelles can be found in both plant and animal cells? a chloroplast b mitochondria c cell wall d lysosomes 34. this organelle is responsible for transcribing rna into amino acids in order to synthesize proteins a nucleus b golgi apparatus c mitochondria d ribosomes 35. what macromolecule do we use to recharge adp back into atp? a protein b lipid c carbohydrate d nucleic acids

Explanation:

1. Active transport requires energy input from the cell to move particles against their concentration gradient.
2. The diagram shows vesicles fusing with the cell - membrane to release contents outside the cell, which is exocytosis.
3. Molecules that are too large to pass through the lipid bilayer by simple diffusion use facilitated diffusion through transport proteins.
4. In a hypertonic solution, water moves out of the cell (or in this case, the egg), causing it to shrink.
5. The cell in the image is swelling, which indicates it is in a hypotonic solution where water is moving into the cell.
6. Mitochondria are present in both plant and animal cells and are the power - houses of the cell.
7. Ribosomes are responsible for translating RNA into amino acids to synthesize proteins.
8. ATP is recharged from ADP using energy from the breakdown of glucose (a carbohydrate).
