| What way to molecules move in active transport? | Low concentration to high concentration
🗑
|

| What way to molecules move in passive transport? | High concentration to low concentration
🗑
|
||||
| Which uses ATP, active or passive transport? | Active transport
🗑
|
||||
| Examples of active transport? | Endocytosis and Exocytosis
🗑

| What is the cell membrane made of? | Lipids + Phosphates = Phospholipids and proteins
🗑
|
||||
| What happens when a cell is in a hypertonic solution? | The cell shrinks as water goes out
🗑
|
||||
| What happens when a cell is in a hypotonic solution? | The cell grows as water goes in
🗑
|
||||
| What happens when a cell is in a isotonic solution? | The cell stays the same as water goes equally in and out
🗑
|
||||
| What is facilitated diffusion? | The gated channel in a protein uses hormones to help open the channel so diffusion can occur.
🗑
|

| What does selectively permeable mean? | Only molecules of a certain size and smaller can fit through the membrane.
🗑
|

| What does it mean to go along (down) a concentration gradient? | Go from high concentration to low concentration
🗑
|
||||
| What does it mean to go against(up) a concentration gradient? | Go from low concentration to high concentration

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
