This type of transport does NOT require ATP to cross the membrane, however it uses channel proteins to aid particles in going from a region of higher to lower concentration
What is facilitated diffusion?
What is considered the growth phase of interphase?
G1
All cells have this flexible outer barrier that is made of phospholipids.
What is the cell membrane?
This type of cell transport requires energy and is known as cell eating.
What is phagocytosis?
What is one reason that cells go through the process of mitosis?
To replace old cells, for growth or for repair
During the mitotic phase, what is the order of the phases
Prophase, metaphase, anaphase, and telophase
This is the job of cyclin B
What is to promote the condensation of chromosomal and spindle assemby?
When do spindle fibers appear?
Late Prophase/Early Metaphase
This cyclin works with Cyclin D during the G1 phase to coordinate cell growth.
What is CDK4?
Uncontrolled cell growth can also be called
Cancer
Some cells stop the cell cycle in what stage of interphase?
G1 or G2
This protein is known as the "Guardian of the Genome."
What is p53?
There is more sodium outside the cell and more water inside the cell. Water moves outside of the cell to find an equilibrium causing the cell to shrink.
What is hypertonic?
This organelle is known as the cell's recycler
What are lysosomes?
What best describes the result of DNA replication during S phase?
Two identical DNA molecules are produced. Each one has a strand that is old DNA and one that is new DNA.
This the job of Cyclin D in the G1 phase
What is coordinate cell growth?
The sodium-potassium pump is a type of active transport. This is the movement of sodium and potassium into and out of the cell and the amount of atp needed.
What is three sodium in, 2 potassium out, 1 atp
These are the proteins that allow water to enter and exit a cell
What are aquaporins?
This organelle is in charge of cellular respiration where the majority of ATP comes from
What is the mitochondria?
