All forms of passive transport involve what?
Diffusion
What are the three types of cell junctions?
Tight, gap, desmosomes.
What might uncontrolled hyperplasia lead to?
Cancer or other diseases
When might Atrophy occur?
Comas
Come up to the board and draw an example of how diffusion occurs
What are cell juntions?
Cells are put together in an orderly matter, not randomly.
What three things influence speed of diffusion?
Particle size, temperature, and concentration gradient.
When might Apoptosis need to occur?
When your body has bad or damaged cells (such as cancer cells) that need to be deleted
What do alpha secondary structure proteins usually turn into?
Fibrous proteins
What do beta secondary structure proteins usually turn in to?
Globular proteins
What is vesicular transport?
Items enter into the cell through vesicles and are used by the cell and the wastes are eventually exported out of the cell.
When might hyperplasia need to occur?
As a child or when you receive an injury
All cells have what three basic parts?
Plasma Membrane, Cytoplasm, and Nucleus
What is the role of Glycocalyx?
They handle cell-environment interactions such as chemical and contact signaling
What are the 6 parts to cell theory?
All living organisms are made of cells
Cells arise from preexisting cells
All cells have the same basic chemical composition
Cells are the basic units of life
Hereditary information is passed from cell to cell
Energy flow occurs within cells
What is secondary active transport?
"Hitchhikers"
Different substances come into the cell once the artificial concentration gradient is created from the primary active transport.
Come up to the board and draw the four levels of protein structure. BE SPECIFIC!!!!!!!!!
What is the main thing Enzymes do to speed up chemical reactions and why is this a good thing?
Lower activation energy
Lower activation energy allows us to do more chemical reactions and/or preserve energy (ATP)
Defend this statement: Energy Flows occurs in cells.
