A distinguishing feature of a plant cell, compared to an animal cell.
What is a central vacuole?
The process by which a cell engulfs large particles.
What is phagocytosis?
A component of the plasma membrane that plays an important role in cell-to-cell recognition.
What is a glycoprotein?
This mathematical relationship explains why cells must remain small, as it decreases when cell size increases, limiting the efficiency of nutrient uptake and waste removal across the cell membrane.
What is SA:V ratio?
Water moves from a low concentration of solutes to a high concentration to do what?
What is dilute the solutes?
Fundamental difference between prokaryotic and eukaryotic cells.
What is the absence of a nucleus?
Molecules moving in what direction causes a cell to use active transport.
What is from low -> high?
This plasma membrane is made up of two layers of phospholipids. Phospholipids are made up of two parts, a hydrophilic head and a hydrophobic tail. What is this phenomenon called?
What is amphipathic?
Calculate the SA:V ratio for a spherical cell with a radius of 5μm.
4/3 * pi * r3
What is 0.60?
The type of solution a cell is placed in that bursts animal cells but leaves plant cells functioning normally.
What is hypotonic?
An aspect of the mitochondria that allows it to be highly efficient at glycolysis (energy production).
A type of transport that would move a small, uncharged, polar molecule.
What is simple diffusion?
A component of phospholipids that allows for membrane stability across a variety of temperatures.
What are the double bonds (kinks) in the phospholipid tails?
SA:V ratio for a cuboidal cell with a side length of 7μm
6s2/s3
What is 0.86?
Solution in which cells show dynamic equilibrium.
What is isotonic?
A cell that has a high rate of protein synthesis would have a large amount of this organelle.
What are ribosomes?
Water can enter the cell in two ways. Name both ways water can enter a cell.
What is simple diffusion through the membrane & via facilitated diffusion through an aquaporin?
The inside of a channel protein is _______ to allow substances to move through the channel.
What is hydrophilic?
A higher SA:V ratio indicates this about the cell.
What is efficent exchange of materials across the plasma membrane?
The NaCl concentration of red blood cells is 154 mM. Predict what would happen if the cell were placed in a 220 mM NaCl solution.
What is RBC will shrivel?
Nucleus -> Rough ER -> Golgi -> Secretory Vesicle - > Plasma Membrane
In a NA/K pump, the pump returns to its original configuration by the reattachment/detachment of this molecule.
What is phosphate?
During receptor-mediated endocytosis, the plasma membrane must......
What is maintaining fluidity while forming vesicles?
A lower SA:V ratio indicates this about the cell.
What is storage of materials?
The concentration of an NaCl solution is 0.5 M. This solution is in a beaker sitting on your desk in the open air. Calculate the solute potential at 22°C
