Endocytosis
the process by which large molecules are taken into the cell
Prophase
•Centrioles duplicate and form spindle microtubules
•Move to opposite ends
•Replicate DNA to form chromosomes
•Chromosomes move to center of cell at the equatorial plane
Function of glycoprotein
Identification
Ribosomes
synthesize proteins
What type of tissue is cartilage in your joints?
Connective
Exocytosis
transport of material from inside the cell to outside the cell using vesicles: secretion
•Metaphase
•Spindle attach to chromosome
Function of receptor protein
Receives messages from other cells
Lysosome
Breaks down proteins, polysaccharides, nucleic acids, and lipids
What two organ systems are most involved in controlling the negative-feedback systems of the body?
Nervous system and endocrine
Histology
study of tissues
Telophase
Plasma membrane constricts and pinches the cell into two cells
In Fluid Mosaic Model, what does fluid refer to and what does mosaic refer to?
Fluid- oily part of membrane composed of phospholipids
Mosaic- different proteins throughout phospholipid layer
Nucleus
Contain DNA and is control center
Protein enters a cell. Outside cell higher concentration than inside cell. Protein entered by active transport or passive transport?
Active large size
Gross Anatomy
study of macroscopic structures of an organism
•Anaphase
•Duplicate and original separate and go to opposite sides of cell
How does a substance get through the plasma membrane? list 4
Channel protein (water)
pinocytosis (proteins)
charged channel proteins (ions)
Carrier Proteins (glucose)
phagocytosis (bacteria)
dissolve through phospholipids (fat)
Golgi Apparatus
Packages molecules for secretion
Heart rate elevates. In negative-feedback system does heart rate go up or down? In positive feedback, does it go up or down?
Negative- down
Positive-up
Physiology
study of functions of an organism and its parts
Interphase
Cell in normal stage and no mitosis taking place and it has no distinguishable chromosomes
What type of protein will a Mg2+ ion use to get into the cell?
Charged channel protein
Mitochondria
Produce energy for the cell
General term for processes in environment that threaten homeostasis
Stress
