In eukaryotes, the citric acid cycle takes place in the? - CORRECT ANSWER -mitochondrial matrix
Which choice below correctly matches organelle with function?
a- capsule- energy production
b- chloroplasts- lipid storage
c- ribosomes- protein synthesis
d- cilia- storage of carbohydrates - CORRECT ANSWER -c- ribosomes- protein synthesis
Which choice below correctly matches organelle with function?
a- lysosome- vesicle full of digestive enzymes
b- smooth ER- extensions of plasma membrane; sweep debris away
c- mitochondria- protein secretion
d- cytoskeleton- recycling of materials - CORRECT ANSWER -a- lysosome- vesicle full of digestive
enzymes
Which choice below correctly matches organelle with function?
, a- GA- vesicles full of digestive enzymes
b- rough ER- surrounds contents of the cell
c- cell wall- can be composed of peptidoglycan, chitin, or cellulose
d- nucleus- lipid synthesis and drug detoxification - CORRECT ANSWER -c- cell wall- can be
composed of peptidoglycan, chitin, or cellulose
You isolate a cell with the following characteristics: no nucleus, a cell wall, and 2 micrometers in
size. This could be a? - CORRECT ANSWER -prokaryotic bacteria cell
You isolate a cell with the following characteristics: nucleus, no cell wall, and 50 micrometers in
size? - CORRECT ANSWER -eukaryotic animal cell
Which correctly matches cell structure with function?
a- granules- type of glycocalyx that functions to help cells adhere to each other
b- inclusions- vesicles full of digestive enzymes in eukaryotic cells
c- cell wall- phospholipid bilayer

Which correctly matches cell structure with function?
a-flagella- composed of pilin; functions in cell attachment to surfaces and other cells
b- plasmid- extrachromosomal DNA, often contains advantageous genes rather than essential
genes, many copies per cell
c- cytoskeleton- all contents inside of the cell, except for the nucleus
d- capsule- located inside of eukaryotic but not prokaryotic cells, makes ATP - CORRECT ANSWER
-b- plasmid- extrachromosomal DNA, often contains advantageous genes rather than essential
genes, many copies per cell
