exam 1 pt4 Flashcards
What are carbon rings like estrogen and essential for reproduction, and cholesterol. The more saturated fats we eat what happens?
Steroids/ The more cholesterol your liver makes.
What creates hydrophobic material to keep water out of our body?
Waxes
What is the small unit of life?
A cell
What does plant cells have? One kind of cells are animal and plant cells?
Have cell wall / Both are eukaryotic cells.
What do all cells have? / What do make ?
Cell membrane / phospholipid bilayer
Receptor proteins do what? Enzyme helps do what? Transport what do? gated do what? Recognition will do what? and Adhesion allows what?
Receive a signal and trigger response in the cell / start a chemical reaction by breaking or building things up/ allows molecules in and out like a good cop / Gated is bad and let molecules go in and out at certain times/ recognize wrong cells/ cells to stick together.
What does the membrane do to the cell? Hydrophilic heads interact with what? Hydrophilic heads like water and the hydrophobic tails try to what?
Deep membrane surrounds the entire sphere of cell. / The inside and outside of the cell/ Repel the water
Now that you have the protein and the lipids that you read where do you go from here?
You go to the gold apparatus which is like a post office and that is where the protein and lipids get pushed out and fused with this cell membrane and get released.
Can molecules and ions still go through the cell wall?
yes, it is just there for structure.
Where does the nuclear envelope go after leaving the ER?
It goes to the nucleus and makes the needed protein then goes to the smooth E R and makes our lipids and fats.
What builds up of proteins and happens in the brain and prevents brain cells from talking to other brain cells and eventually loses other bodily functions causes memory loss?
Plack
What of work is what an organelles job needs to do. What in the body trigger proteins and the proteins (ER is covered in by what and are where proteins are made.)
Distribution/ Hormones/ Covered in ribosomes.
What does protein do in the cell when you take medicine?
It will come in and prevent the hydrogen ions coming to the cell.
Lysosomes break down large molecules and do what? What kind of cell are they in?
They get rid of anything that we do not need. / Lysosomes are in the animal cell
What do Peroxisomes do?
Break down toxic molecules and fatty acids.
