Mitosis
This phase of mitosis results in equal and identical copies of DNA on opposite poles of the cell.
What is a vacuole?
During diffusion, molecules move from a _____ concentration to a ______ concentration
High to Low
Cells undergoing DNA replication are in this phase of the cell cycle
S phase
A high surface area to volume ratio results in this cell size
What is a small?
This is one of the key role of mitosis
What is tissue repair, growth, or asexual reproduction?
Synthesizing lipids like oils and steroids are a main function of this organelle.
What is the smooth ER?
Large nonpolar molecules are able to enter the cell through this kind of transport.
What is facilitated transport?
Also known as programmed cell death, the activation of the p53 gene can result in this.
What is apoptosis?
This triple membraned organelle has a folded innermost membrane that increase ATP synthesis
What is a chloroplast?
Two new nuclei form during this stage of Mitosis.
What is Telophase?
This organelle can release its digestive enzymes to initiate apoptosis
What is a lysosome?
These small and polar molecules can travel freely across the membrane with the concentration gradient in small amounts
What is water or urea?
These two proteins are responsible for positive regulation of the cell cycle.
Cyclin and Cyclin Dependent Kinase
The lysosome is supported by this specific environment
During this phase DNA condenses into chromosomes and the nuclear envelope degrades
What is prophase?
These two organelles are located near the nucleus and are responsible for protein synthesis and folding.
What are ribosomes and rough ER?
Large molecules that cannot pass through the phospholipid bilayer must pass through these.
What are transport proteins?
This checkpoint ensures DNA was replicated correctly
G2 checkpoint
This organelle's folded membrane supports protein modification and transport via vesicles.
What is the Golgi apparatus?
Lack of regulation in this phase can result in nondisjunction
What is metaphase
This organelle is a series of flattened membranes. Cell products pass through these membranes and become packaged for delivery in or out of the cell.
What is the Golgi apparatus?
Movement of NaCl into the cell against the concentration gradient would require these TWO components
What is ATP and transmembrane protein
What is G0?
MPF promotes the initiation of mitosis by phosphorylating target proteins. How does phosphorylation change protein function?
Change in protein shape or conformational change
