Unit 3 test. study guide biochem John silva
ADP
(Adenosine Diphosphate) The compound that remains when a phosphate group is removed from ATP, releasing energy
epithelial tissue
A body tissue that covers the surfaces of the body, inside and out
connective tissue
A body tissue that provides support for the body and connects all of its parts
Tissue
A group of similar cells that perform the same function.
Fungi
A kingdom made up of nongreen, eukaryotic organisms that have no means of movement, reproduce by using spores, and get food by breaking down substances in their surroundings and absorbing the nutrients
Virusus
A program that secretly attaches itself to a legitimate "carrier" such as a document or program, and then executes when document is opened or program is launched.
Phagocytosis
A type of endocytosis in which a cell engulfs large particles or whole cells
Pinocytosis
A type of endocytosis in which the cell ingests extracellular fluid and its dissolved solutes.
Enzyme
A type of protein that speeds up a chemical reaction in a living thing
smooth muscle
Involuntary muscle found inside many internal organs of the body
cardiac muscle
Involuntary muscle tissue found only in the heart.
serous membrane
Membrane that lines a cavity without an opening to the outside of the body
mucous membrane
Membrane that secretes mucus that lubricates the surface of organs and keeps them moist.
Exocytosis
Process by which a cell releases large amounts of material
cellular respiration
Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
ATP in cells
a cell's ATP is recycled every minute; humans use close to their body weight in ATP daily (1 muscle cell can require 10 million ATPs a second), no ATP production=quick death
Cyanide
a common product of combustion, stops energy production by cells. inhabits oxygen from binding on RBC
Microorganisms include
bacteria viruses fungi protozoa helminths (worms) algae
Adenosine Triphosphate (ATP)
compound used by cells to store and release energy
Membranes
flat sheets of pliable tissue that cover or line a part of the body
skelatal muscle
muscles attached to the bones of your skeleton, and provides the force that moves your bones
Neurons
nerve cells
Protozoa
one-celled organisms that are more complex than bacteria
Mitosis
part of eukaryotic cell division during which the cell nucleus divides
Endocytosis
process by which a cell takes material into the cell by infolding of the cell membrane
collagen fibers
provides flexibility and strength
brain controls
sensation, perception, movement, thinking
Bacteria
single-celled organisms that lack a nucleus; prokaryotes
cutaneous membrane
skin
Meninges
three protective membranes that surround the brain and spinal cord
