100
What are flexion, rotation, lateral diffusion, and rarely flip flop?
These are the 4 ways in which phospholipids can move in the phospholipid bilayer of the cell membrane.
100
What is molecular size and solubility?
The rate of diffusion of molecules across the cell membrane depends on these two factors.
100
What is Adenosine Triphosphate (ATP)?
This is the name of the most abundant activated carrier in cells.
100
What is metabolism?
This term is defined as the sum of chemical reactions within a cell that provide energy for life.
200
What is a liposome?
This is formed when the phospholipid bilayer spontaneously closes to form a more energetically favorable structure.
200
What is electrochemical gradient?
Active transport with the use of ATP goes against this gradient.
200
What is reduction; oxidation?
______ is a reaction consisting of the gain of electrons, whereas ______ is a reaction consisting of the loss of electrons.
200
What is pyruvate?
This is the name given to the product of glucose oxidation in glycolysis.
300
What is cholesterol?
This molecule fills gaps in the phospholipid bilayer and stiffens it, changing fluidity based on temperature.
300
What is a voltage gated cation channel?
Neuron action potentials are mediated by this type of ion channel.
300
What is glycolysis?
This reaction turns 1 glucose into 2 pyruvate.
300
What is the mitochondrial intermembrane space?
The proton gradient that powers ATP synthase can be found in this area of the mitochondria.
400
What is the cell cortex?
This thing reinforces the plasma membrane and facilitates membrane domains.
400
What are neurotransmitters?
These convert an electrical signal into a chemical signal at the neuron synapse during an action potential.
400
What is gluconeogenesis?
This process uses specific enzymes to bypass irreversible steps of glycolysis.
400
What is the Electron Transport Chain?
If this process comes to a stop there would be an influx of NADH and oxygen would not be reduced.
500
What is scramblase?
This enzyme catalyzes the transfer of random phospholipids from one monolayer to the other.
500
What are Na+ and Ca+2, what is K+?
These two ions have a higher concentration outside of the cell, and this ion has a higher concentration inside of the cell.
500
What is Acetyl Co A; CO2?
The citric acid cycle completely oxidizes carbon from what to what?
500
What is NADP+?
Constant regeneration of this molecule allows for the continuous synthesis of ATP.
