bio keystones: Homeostasis and Transport
Terms in this set (81)
This is a neurotransmitter at neuromuscular junctions, at synapses in the ganglia of the visceral motor system, and at a variety of sites within the central nervous system. It was the first neurotransmitter discovered.
Process requiring energy for the movement of particles across a cell membrane against the concentration gradient.
All Or Nothing Response
This states that the strength of a response of a nerve cell or muscle fiber is not dependent upon the strength of the stimulus. If a stimulus is above a certain threshold, a nerve or muscle fiber will fire. Essentially, there will either be a full response or there will be no response at all.
This is a type protein produced by the immune system that detects foreign substances or antigens like bacteria and viruses.
This is the main energy storage and transfer molecule in the cell.
This is what we are referring to when we say an animal is either warm blooded or cold blooded. It is one aspect of homeostasis.
This is an organ of the central nervous system, which has three distinct parts that control and coordinate the activities of the body. The cerebrum controls thoughts, voluntary actions, and the sensations related to the five senses. The cerebellum helps with balance and coordination. The stem controls vital and involuntary processes like breathing and your heart beating.
A solution in which the pH remains relatively constant when small amounts of acid or base are added; this can be either a solution of a weak acid and the salt of a a weak acid or a solution of a weak base with the salt of a weak base.
This is the structural and functional unit of all living organisms, and are sometimes called the "building blocks of life."
A thin, flexible, semipermeable barrier around the cell which regulates what enters and leaves the cell.
This system transports blood through the body and heart.
This is the unequal distribution of ions across a cell membrane.
These are folds in the mitochondria that contain enzymes important to ATP production and also increase the surface area for ATP production.
This is a short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body.
The process when molecules tend to move from an area of high concentration to an area of low concentration.
This system prepares food for cellular utilization.
This system controls the glands that secrete hormones.
This is the process where cells engulf material from outside their cell membranes.
This is a membrane
bound organelle in eukaryotic cells that is the production and processing center of proteins and some lipids.
These are complex proteins that speed up chemical reactions by lowering the amount of energy needed to get the reaction started.
This is the transport of material out of a cell by means of a sac or vesicle that first engulfs the material and then is extruded through an opening in the cell membrane.
This is a process by which substances are transported across cell membranes by means of protein carrier molecules.
This is a mechanism by which organisms maintain homeostasis when the level of one substance influences the level of another substance or the activity of an organ.
This is a neurotransmitter that acts in an inhibitory manner, tending to cause nerves to calm down.
These are a group of organs in the endocrine system that synthesize substances needed by the body (hormones)and release it through ducts or directly into the bloodstream.
This organelle serves to process and package lipids and proteins in the cell.
Chloroplast thylakoids are frequently stacked to form these disks.
This is the major organ of the circulatory system that causes blood to flow through the body by its pumping action.
This is a regulation of the internal environment of an organism.
This is a chemical substance made by glands in the endocrine system that travel through the bloodstream and affects cells and tissues throughout the body.
A solution that causes a cell to shrink because of the high concentration of solute in the solution surrounding the cell.
A solution that causes a cell to swell because of osmosis.
This is a system of biological structures and processes within an organism that protects against disease.
When the concentration of solute and solvent are equal on both sides of the membrane.
This is a bean
shaped organ which is responsible for filtering blood and regulating fluid within the excretory system.
This is one of the main organs of the respiratory system where gases are exchanged between air and the blood.
These are organelles that digest macromolecules.
This is a type of protein found in the cell membrane, which regulates the coming and going of substances into or out of the cell.
This system receives and transmits information and responses. It depends upon electrical impulses created by the movement of charged particles.
This is any functional structure within the confines of a cell; literally a. "small organ;" it usually has a membrane
This is a process in which water moves through a membrane, from an area of high concentration to an area of lower concentration.
energy requiring process that moves materials across a cell membrane with the concentration gradient.
These are disease
causing cells or organisms.
This is the ability to allow certain ions or chemicals into or out of a cell.
This is the scale used to describe how acidic or basic a solution is. This affects the enzymes within living systems.
This is found in cell membranes and help protect the cell or organelles by allowing/not allowing molecules to enter.
This organ is considered the main gland of the endocrine system and produces hormones that regulate metabolism, growth, and maturation.
This is the uneven distribution of bonding electrons in a molecule creating partially positive and negative sides of that molecule.
This gland found in males produces the fluid component of semen.
A macromolecule that contains carbon, hydrogen, oxygen, and nitrogen, which is used by the body for growth and repair.
This system gets oxygen to the cells of the body and rids the body of waste gases. Some organisms use their skin. This is also a cell
This is a biological reaction due to a stimulus.
This organelle synthesizes proteins.
Rough Endoplasmic Reticulum
This organelle complex functions to compartmentalize the cell, serves as mechanical support, provides site
specific protein synthesis with membrane
bound ribosomes and plays a role in intracellular transport.
These are the principal glia of the peripheral nervous system (PNS).
This is an ability of a plasma membrane to allow some substances to cross across the membrane more easily than others.
This is a nerve cell that transmits sensory information and send projections to other elements of the nervous system, ultimately conveying sensory information to the brain or spinal cord.
This is the point at which increasing stimuli trigger the start of an afferent nerve impulse.
Sodium Potassium Pump
This is an active transport mechanism by which cells pump sodium and potassium ions against the concentration gradient.
The substance that dissolves the solute.
This is the action that causes a response.
This is the colorless fluid surrounding the grana within the chloroplast.
Sympathetic Nervous System
This is one of three parts of the autonomic nervous system. Its general action is to mobilize the body's nervous system fight
flight response. It is also constantly active at a basic level to maintain homeostasis.
This is a membrane
bound compartment inside chloroplasts and cyanobacteria. They are the site of the light
dependent reactions of photosynthesis.
This is one of the largest glands in the endocrine system that produces and stores hormones that regulate heart rate, blood pressure, body temperature, and the metabolism rate.
This is a tiny fluid
filled cavity in the cytoplasm. It can be used for storage of biochemicals.
Two parts hydrogen and one part oxygen, this polar molecule is responsible for life on earth.
White Blood Cell
This is a cell of the immune system that defends the body against both infectious disease and foreign materials. Also called leucocytes.
