Bio 115 exam 2 2022 Flashcards
You’re studying an unknown cell type. After looking under a microscope, you found that it contains a membrane-bound nucleus, ribosomes, and mitochondria. Based on this information, what can you reasonably conclude?
The cell is a eukaryote.
You’re studying an unknown cell type. After looking under a microscope, you notice the cell has a cell wall. Based on this information, what can you reasonably conclude?
The cell is a plant cell.
You’re studying an unknown cell type. After looking under a microscope, you notice the cell has a membrane-bound nucleus and lysosomes. Based on this information, what can you reasonably conclude?
The cell could be either a plant cell or an animal cell.
What component of the endomembrane system deposits proteins into the ER?
Ribosomes
Vesicles are carried through the endomembrane system by ______
Kinesin motor proteins
True or false? Plant cells contain both mitochondria and chloroplasts.
True
ATP Synthase sits in the ___________ of the ___________.
The inner membrane; mitochondria.
Photosynthesis takes place at which locations?
The thylakoids and stroma of chloroplasts.
An animal cell is depleted of all ATP. What molecule isn’t working?
ATP synthase
Which description below best explains why mitochondria have their own unique DNA separate from the cell?
We theorize that a large primitive eukaryote swallowed a heterotrophic prokaryote, but didn’t digest it.

A disruption to vesicle transport is most likely affecting…
Microtubules
What ECM molecule will you most likely find embedded in the plasma membrane?
Integrins
What ECM molecule is responsible for padding and cushioning the area between cells?
