Cell Transport Notes

A sudden drop in external temperature

Stable blood sugar levels

Constant internal pH

Consistent body temperature

Homeostasis allows organisms to maintain stable internal conditions.

To help maintain homeostasis by responding to stimuli

To help maintain homeostasis by increasing the rate of cell division

To help maintain homeostasis by producing energy for cellular processes

To help maintain homeostasis by transporting materials across the cell membrane

Active transport moves with the concentration gradient.

Passive transport moves against the concentration gradient.

Active transport moves against the concentration gradient.

Passive transport moves with the concentration gradient.

It gets dissolved in another substance.

It does the dissolving in a solution.

It is always a solid.

It increases the concentration gradient.

It requires energy to move molecules against the gradient

It moves molecules with the gradient without energy

It only transports water molecules

It does not use protein channels
