This is a localized area where the chromosome locates and is not membrane bound.
What is nucleoid?
100
This is a complex of RNA and proteins.
What are ribosomes?
100
These are two functions of the cytoskeleton.
What is provide structural support and movement to alter shape or shift contents?
100
1. Ribosome deposits protein into ER
2. Protein exits ER
3. Protein enters Golgi for processing
4. Protein exits Golgi
5. Protein exits cell.
These steps are part of the __________________________ hypothesis.
What is the secretory pathway hypothesis?
100
This type of cell exports digestive enzymes.
What is a pancreatic cell?
200
This is a small, double-stranded, circular DNA that encodes proteins and may allow for adaptation to different environments.
What is a plasmid?
200
This contains enzymes for synthesizing lipids.
What is the smooth ER?
200
These are the three parts to the cytoskeleton.
What are actin filaments, intermediate filaments, and microtubules?
200
This predicts that proteins bound for the endomembrane system will have a molecular zip code for
the destination, like the nuclear localization signal.
What is the signal hypothesis?
200
These are packed with smooth ER and they export lipid-soluble signals.
What is an animal testis cell?
300
These are three tasks performed by bacterial organelles.
What is store calcium ions, store crystals of magnetite, and contain enzyme complexes?
300
These contain proton pumps and functions in digestion of old cell components.
What are lysosomes?
300
This maintains cell shape by resisting tension and divides animal cells in two.
What are actin filaments?
300
This happens approximately every 10 days.
What is replacement of the mitochondria?
300
In plants, this produces ATP and sugar.
What is a leaf cell?
400
These are formed from the infolding of the plasma membrane in bacterial cells.
What are photosynthetic membranes?
400
This functions in glycosylation.
What is the Golgi apparatus?
400
This protein walks along a microtubule in order to move vacuoles in the cell.
What is kinesin?
400
This type of molecule is tightly regulated as it moves throughout the cell.
What are proteins and large molecules?
400
In plants, this stores starch.
What is a root cell?
500
The cytoplasm is ________________ relative to outside environment.
What is hypertonic?
500
These contain transporters for selected macromolecules.
What are peroxisomes?
500
These slide along the microtubule when coupled with ATP to enable flagella and cilia to move.
What are dynein arms?
500
These contain acid hydrolases.
What are lysosomes?
500
This is the addition of a carbohydrate to a protein.
