•Active Transport

10

Cell must use energy to move molecules across membrane

-Usually against a concentration gradient

-Pay cash to get into a crowded club

Ex. Getting into the clubOR Swimming against the current

-Moves from Low to High concentration

Active Transport

Active Transport

-Uses energy

-Moves bigger particles with carrier proteins

ATP

•PASSIVE TRANSPORT

13

Cell does not need to use energy to move molecules across membrane -Usually with a concentration gradient

-Free to exit a crowded club

Ex. Getting out of the clubOR Floating with the current

Activity 1. Passive vs. Active Grid

Activity 2: Passive and Active Venn Diagram

Activity 3: Passive and Active Situations (Schoology)

Active Transport

Passive Transport

Fill in the Venn Diagram Below. Some things to consider as you fill it in….. -size of molecules -energy -carrier/transport proteins used -concentration gradient – Direction particles move -Types - What is the purpose of Transport You should also include at least 3 of your own ideas of how they are alike and different that are not from the list above.
