Resumen del Recurso

Pregunta 1

Pregunta
The two things that break down membranes are [blank_start]temperature[blank_end] and [blank_start]organic[blank_end] [blank_start]solvents[blank_end]
Respuesta
  • temperature
  • organic
  • solvents

Pregunta 2

Pregunta
An increase in temperature results in more [blank_start]kinetic[blank_end] [blank_start]energy[blank_end]. An increase in movement results in more [blank_start]fluidity[blank_end] and permeability
Respuesta
  • kinetic
  • energy
  • fluidity

Pregunta 3

Pregunta
The phospholipids [blank_start]vibrate[blank_end], causing them to get further apart. Once there are bigger gaps in the membrane, larger molecules can pass through
Respuesta
  • vibrate

Pregunta 4

Pregunta
Very high temperatures completly break down the membrane
Respuesta
  • True
  • False

Pregunta 5

Pregunta
[blank_start]Ethanol[blank_end] is an organic solvent
Respuesta
  • Ethanol
  • Glucose
  • Water

Pregunta 6

Pregunta
Ethanol dissolves the [blank_start]lipids[blank_end] in the membrane as it is [blank_start]less[blank_end] polar than water, making the membrane lose its [blank_start]structure[blank_end]
Respuesta
  • lipids
  • less
  • structure
