Final Flashcards
Which cell structure contains the cell’s genetic material and controls many of the cell’s activities?
Nucleus
Which organelle breaks down compounds into small particles that the cell can use
Lysosome
Which organelle makes proteins using coded instructions that come from the nucleus
Ribosome
Which organelle converts the chemical energy stored in food into compounds that are more convenient for the cell to use?
Mitochondrion
What is the function of the cell membrane?
Regulates which materials enter and leave the cell
The thin, flexible barrier around a cell is called the
Cell membrane
What is the function of the nucleus
Stores DNA
Controls most of the cell’s processes
Contains the info needed to make proteins
Which of the following is a function of the cytoskeleton
Helps a cell keep its shape
Diffusion is the movement of particles from
An area of high concentration to an area of low concentration
The diffusion of water across a selectively permeable membrane is called
Osmosis
A group of similar cells that perform a particular function is called a
Tissue
Which of the following is not a stage of cellular respiration?
Fermentation
Electron transport
Glycolysis
Krebs cycle
Fermentation
The Krebs cycle produces
Carbon dioxide
Cellular respiration uses one molecule of glucose to produce
36 ATP molecules
What is a product of cellular respiration
Water
Glycolysis provides a cell with a net gain of
2 ATP molecules
Electron transport chain occurs in the
Mitochondria
The energy of the electrons passing along the electron transport chain is used to make
ATP
DNA replication results in two DNA molecules
Each with one new strand and one original strand
Unlike DNA, RNA contains
Uracil
Which types of RNA are involved in protein synthesis
Messenger RNA, ribosomal RNA, and transfer RNA
What is produced during transcription
RNA molecules
What happens during the process of translation
The cell uses information from messenger RNA to produce proteins
What is the major difference between facilitated diffusion and active transport
Active transport moves substances against the concentration gradient
