Bio Exam Ahh!!!

Front 1

Passive transport

Back 1

Is moved across the cell membrane that does not require energy from the cell

Front 2

Concentration gradient

Back 2

Is the described as the amount of cells moving back and forth the cell membrane.

Front 3

Equilibrium

Back 3

Is the condition which the concentration of substance is equal throughout space.

Front 4

Homeostasis

Back 4

Is when organism adjust internally to changing external conditions.

Front 5

Diffusion

Back 5

Is the movement of cells to establish equilibrium

Front 6

Active transport

Back 6

Is the movement of substance across the cell membrane that requires energy

Front 7

Water is

Back 7

Polar

Front 8

Water ALSO

Back 8

Expands whin freezes and is less dense as a solid than as a liquid This is why ice floats

Front 9

Diffusion

Back 9

Does not require energy from the cell or any other source It just happens TEMPITURE an increase of tempiture will cause diffusion to happen more quickly. Presure in crease in pressure makes diffusion happen more quickly

Front 10

Osmosis

Back 10

The diffusion of water

Front 11

Solutions

Back 11

Mixture of two parts: solute & solvent

Front 12

Solute

Back 12

The molecules that are dissolved

Front 13

Solvent

Back 13

The molecules They are dissolved IN

Front 14

Isotonic solution

Back 14

Solution has the same concentration of solute molecules as the cell
Solution remains UNCHANGED

Front 15

Hypertonic solution

Back 15

Cell looses water and shrinks

Front 16

Hypotonic Solution

Back 16

Cell gains water and swells and can even burst

Front 17

Facilitated transport

Back 17

Transport proteins help substances move across the membrane diffusion

Front 18

Active transport

Back 18

Movement of molecules that REQUIRES ENERGY

Front 19

Endocytosis

Back 19

Material engulfed by a portion of the plasma membrane

Front 20

Exocytosis

Back 20

Cell expels wastes. Out of

Front 21

Photosynthesis

Back 21

Process by which autoraphs convert sunlight to a usable form of energy

Front 22

Chloroplast

Back 22

Has in it photosynthesis

Front 23

Chemical equation of photosynthesis

Back 23

Light
6CO2+6 H2O --->Co H12 O6+6O2
energy

Front 24

Calvin cycle

Back 24

Does not require light in order to occur. Products of the light reactions and carbon dioxide are required to produce sugar

Front 25

1 glucose iss produced for every

Back 25

6 molecules of co2

Front 26

Cellular respiration

Back 26

Process by which glucose molecules are broken down to relese energy

Front 27

What does ATP mean

Back 27

Adenosine triphosphate

Front 28

Chemical equation of cellular respiration

Back 28

C6 H12 O6+6 O2 ----> 6CO2 + 6H2O + energy

Front 29

The 2 places whare cellular respiration takes place.

Back 29

The main organal is the mitochondria and siteoplasm

Front 30

Glycolysis

Back 30

Oxygen is not Required. It occurs in the cytoplasm of the cell and produces a net yield of two NADH two ATP and two pyruvate molecules

Front 31

Krebs cycle

Back 31

also called the citric acid cycle because the first reaction forms citric acid. It produces 2 molecules of ATP per molecule of glucose

Front 32

Electron transport

Back 32

Process by when energy is transferred from NADH2 to ATP. This process requires oxygen and occurs in the inner membrane of the mitochondria. The electron transport chain generates 32 of the 36 ATP molecules produced from each glucose molecule

Front 33

Fermentation

Back 33

Has 2 APT and does not require oxygen and is known as ANAEROBIC.

Front 34

Pyruvate

Back 34

Produces at he end of glycolysis is converted into LACTIC ACID. It prevents the kreb's cycle from operating and causes cramping with in the muscles.

Front 35

Alcoholic fermentation

Back 35

Some organisms produce alcohol as a result of fermentation instead of lactic acid.
