Biology pre lab

Diffusion

The movement of particles or molecules from an area of high concentration to and area of low concentration

Semi-permeable membrane

A thin barrier that allows certain molecules or ions to pass through while blocking others

Concentration gradient

The difference in the concentration of a substance between two connected areas, influencing the movement of molecules during diffusion

Osmolarity

The measure of solute concentration in a solution

Osmosis

The movement of a solvent(water) through a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration

Hyper-osmotic/ hypertonic

A fluid that has a higher concentration of solutes compared to a cell's cytoplasm, resulting in a net movement of water out of the cell across the cell membrane

Hypo-osmotic/ hypotonic

A fluid that has a lower concentration of solutes compared to a cell's cytoplasm, resulting in a net movement of water into the cell across the cell membrane

Iso-osmotic/ isotonic

A fluid that has the same concentration of solutes as a cell's cytoplasm, resulting in no net movement of water across the cell membrane

Plasmolysis

The shrinking of the cytoplasm and plasma membrane away from the rigid cell wall of a plant cell due to water loss in a hypertonic environment

What is the cellular location for glycolysis?

Cytosol

What is the cellular location for aerobic respiration?

Mitochondria

What is the cellular location for photosynthesis?

Chloroplasts

Equation for aerobic respiration

C6H12O6 + 6O2 —> 6CO2 +6H2O +ATP

Equation for photosynthesis

6CO2 + 6H2O —> C6H12O6 +6O2

lower

The more CO2 consumed by a cell, the ___ the pH will be

higher
