Term
ho·me·o·sta·sis
Definition
balanced internal condition
Term
Cell Transport
Definition
the movement of compounds across the outer wall or membrane of the cell.
Term
Any substance passing into or out of cells must pass through the ____ _________
Definition
cell membrane
Term
cell mem·brane
Definition
The semipermeable membrane surrounding the cytoplasm of a cell, Phospholipid. Selectively Permeable.
Term
Pores
Definition
SMALL holes the allow certain things to cross the membrane. Diffusion
Term
Active transport
Definition
the movement of a substance across a cell membrane against its concentration gradient (from low to high concentration).
Term
Passive transport
Definition
a movement of biochemicals and other atomic or molecular substances across membranes. Unlike active transport, it does not require an input of chemical energy
Term
Facilitated diffusion
Definition
the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane integral proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism.
Term
dif·fu·sion
Definition
The spreading of something more widely from high Concentration to low concentration. Is possible because molecules are always moving and randomly colliding. No energy required.
Term
When the molecules are spread out evenly this is called
Definition
equilibrium
Term
Diffusion depends on a ________ ________
Definition
concentration gradient
Term
_______ ________ is the difference in the concentrations of a substance on two sides of a permeable barrier.
Definition
Concentration Gradient
Term
__________ is the amount of a substance present in a mixture or soultion
Definition
Concentration
Term
______ is the movement of water across a membrane from high to low
Definition
Osmosis
Term
Osmosis is ________ transport. No energy required
Definition
passive
Term
Water molecules are found on both inside and outside the cell, water moves for ____ to ____
Definition
High to low
Term
A solution is composed of a _____ and a _______
Definition
solute and a solvent
Term
The ______ is what is dissolved in the solvent.
Definition
solute
Term
Fir osmotic solutions, the _________ is always _____
Definition
solvent is always water.
Term
Solutes are usually ____ or _____
Definition
salt or sugar
Term
Plants use ______ to take in water
Definition
osmosis
Term
The two factors that affect cell transport include _________ and ___________
Definition
Concentration gradient and temperature.
Term
The adaptation for survival in a freshwater environment is possible because of ______________________
Definition
Contractile vacuole
Term
A ________________________ pumps out excess water from the cell.
Definition
Contractile vacuole
Term
Cell adaptation for survival in a Salt water environment is possible because of their_______
Definition
Gills
Term
ATP stands for _________ _________
Definition
Adenosine triphosphate
Term
Adenosine triphosphate is ___ which is ...........................................................................
Definition
A compound consisting of an adenosine molecule bonded to three phosphate groups, present in all living tissue. The breakage of one phosphate linkage (to form adenosine diphosphate, ADP) provides energy for physiological processes such as muscular contraction
Term
ATp stores energy in ________ ________
Definition
Chemical Bonds
Term
Energy is _____________ when a ATP chemical bond is ____________
Definition
Released, Broken
Term
Cellular respiration is ...................................
Definition
the set of the metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products
Term
In eukaryotic cells cellular respiration takes place in the __________
Definition
Mitochondria
Term
The chemical equation for cellular respiration is the _________ of photosynthesis.
Definition
opposite
Term
______ gas is released during cellular repiration
Definition
C02
Term
_______ use C02 during Photosynthesis.
Definition
Plants
Term
The equation for Cellular respiration is _________ + O2 to CO2 + H20 + _______
Definition
glucose, ATP
Term
The main goal of cellular respiration is to create ________
Definition
energy
Term
Aero = Air so there for Aerobic Respiration uses ______________
Definition
Oxygen
Term
_________ __________ uses oxygen to break down sugars. Makes lots of ATP
Definition
Aerobic Respiration
Term
Anaero = no air, therefore Anaerobic respiration uses _______
Definition
no air
Term
Anaerobic respiration is also called ___________________
Definition
fermentation
Term
________ fermentation is a biological process in which sugars such as glucose, fructose, and sucrose are converted into cellular energy and thereby produce ethanol and carbon dioxide as metabolic waste products
Definition
Alchoholic
Term
_________________ fermintation is a biological process by which glucose, fructose, and sucrose are converted into cellular energy and the metabolite lactate. It is an anaerobic fermentation reaction that occurs in some bacteria and animal cells, such as muscle cells.[1][2][3] If oxygen is present in the cell, many organisms will bypass fermentation and undergo cellular respiration
Definition
Lactic Acid
Term
Molecules must pass the _______ __________________ when entering or exiting cell
Definition
Cell Membrane
Term
Cells need to transport substances across the cell membrane because..........
Definition
then need to eat and breath and excrete.
Term
____________ transport requires no energy and includes diffusion and osmosis.
Definition
Passsive
Term
diffusion is possible because .........................
Definition
molecules are always moving and colliding.
Term
_______________ is to describe the equal distribution of molecules against the concentration gradient
Definition
Equilibrium
Term
____________ transport moves molecules against the concentration gradient
Definition
Active
Term
The energy in ATP is stored in the _______ _____________
Definition
chemical bonds
Term
The reactants for cellular respiration are ____________ and _________________
Definition
glucose and oxygen
Term
Both Anaerobic and Aerobic require __________
Definition
Glucose
Term
The differences between Anaerobic and Aerobic is that.............................
Definition
