Y or N Stem cells are identical to each other
Yes
Undifferentiated stem cells that can form into any type of tissue are called
Embryonic Stem Cell
When an enzyme loses it's shape this is called...
Denaturing
The ability to the body or cell to maintain a condition of equilibrium or stability within its internal environment when dealing with external changes
Homeostasis
Uses energy, goes against the concentration gradient and uses a protein channel
Active Transport
Stem cells found in bone marrow can differentiate into certain cells
Adult or somatic stem cells
You find stem cells here
Embryos, umbilical cords and bone marrow
A lock and key
Blood Vessels constrict and cause muscle spasms in an attempt to counteract the environment when the body gets too...
Cold
Doesn't use energy, goes with the concentration gradient
Simple Diffusion
This cell would be specialized with a predominant nucleus, flagella, and mitochondria
Sperm cell
Common cells replaced by stem cells
Blood, skin, muscle, nerve
Enzymes speed up reactions by
Lowering activation energy
Blood vessels dilate and the body secretes fluids when it is too...
Hot
Doesn't use energy, goes with the concentration gradient but is only water
Osmosis
This type of cell would be specialized to have more mitochondria
Muscle cell
Specialization in cells can come in many forms like...
Shape, size, organelles, etc
The pH and temperature that an enzyme works best at is called...
Optimal
When the hormone insulin is released from the pancreas we have too much of this sugar in our body
Glucose
Doesn't use energy, goes with the concentration gradient and uses a protein channel
Facilitated Diffusion
This is how cells become differentiated
Genes are turned on/off
The shape of a nerve cell aids it in this process
Receive/communicate signals
These two factors most often affect enzymes and their denaturing. (You must get both to get the points)
pH & temperature
These solutions keep pH constant in a wide variety of chemical actions, usually a weak base or acid
Buffer
All transport occurs with what cell structure
Cell Membrane
