cell membrane
What does the cell membrane do?
Controls what enters and leaves the cell
This type of transportation doesn't require energy.
(one of two categories)
Passive transportation
This type of cellular respiration occurs without oxygen
anerobic respiration
This type of cell does not contain a nucleus
Prokaryotic
what are the elements all biomolecules have
C,H,O
What is the cell membrane made of?
Phospholipid bilayer
examples of active passport:
Endocytosis, Exocytosis, protein pump
contractile vacuole
regulates water inside the cell
What are some organelles found in all cells
plasma membrane, ribosomes, cytoplasm, and DNA.
The monomer of proteins
amino acids
which part of the cell membrane is hydrophobic?
The tail of the phospholipid.
This happens in osmosis when a cell has more water outside of the cell than inside
A hypertonic solution
what do cilia, flagella, and psuedopods have in common?
They are all used for motion/ movement
What does a eukaryotic cell have that a plant cell doesn't
membrane bound organelles, nucleus
what is the purpose of nucleic acids?
To store genetic information
which part of the cell membrane is cholesterol normally found in?
In between the heads of the phospholipids
This type of passive transport needs proteins to help move larger particles
facilitated diffusion
the breakdown of glucose by enzymes, releasing energy and pyruvic acid.
Glycosis
Who created the first microscope and named cells?
Robert Hooke
What is the shape of DNA and RNA
DNA= double helix
RNA=helix
Facilitated diffusion happens in the cell membrane with the help of ________
Proteins
This type of active transportation helps move large particles out of the cell, and uses a vesicle.
Exocytosis
when you work out, your body uses and alternative way to make energy, from the lack of oxygen. This type of respiration builds up lactic acid in the muscles, what type of respiration is it?
Anerobic
The function of the stem cell
Student answer
hemoglobin and enzymes are an example of:
Proteins
