Needs Energy
Match the vocabulary with the definitions.

Draggable item		Corresponding Item
Endocytosis		A protein that pumps molecules across a membrane from a LOW concentration to a HIGH concentration

The lungs exchange gas with our blood to maintain homeostasis. When we breathe in, there is a high concentration of oxygen in our lungs and a low concentration of oxygen in our blood. Because of this, the oxygen molecules move from the lungs into the blood. This movement of oxygen from a high to low concentration is an example of what type of cell transport?

As a result of Passive Transport, the concentration of many types of substances…

Eventually becomes unbalanced on both sides of a membrane.

Will become higher outside of a membrane.

Eventually becomes balanced on both sides of a membrane.

Will become higher inside of a membrane.

As shown in the picture, the cell membrane is made of two layers of fat molecules. The main function of this organelle is to control what molecules enter and leave the cell so that the cell can maintain homeostasis.
Based on this information, which biomolecule is important for keeping a cell’s internal balance?

Proteins

Lipids

Carbohydrates

Nucleic Acids

Students used vinegar in order to dissolve away the shells of three eggs and used these eggs as models of human red blood cells. The students observed the changes in the eggs when they were placed in different solutions.
Which statement best describes the role of the cell membrane in this model?

The cell membrane is a complete barrier that does not allow water to enter the cell.

The cell membrane allows water to enter and leave the cell, which can affect the size of the cell.

The cell membrane allows sugars to enter the cell, which causes the cell to shrink.

The cell membrane removes sugars and salts from the environment, which causes the cell to grow.

Which statement best explains why the egg in corn syrup lost mass (got smaller)?

The egg had a higher concentration of water than the corn syrup, so water moved out.

The corn syrup has a higher concentration of water than the egg, so water moved in.

The concentration of the water inside the egg is the same as the concentration in the corn syrup.

The egg had a lower concentration of water than the corn syrup, so water moved in.

The cellular process known as the sodium-potassium pump was discovered in the 1950's by Jens Christian Skou, a Danish scientist. This process is a form of active transport that moves three sodium ions to the outside of a cell for every two potassium ions that it moves into the cell.
Which of these best explains why energy is needed for active transport?

Ions are negatiely charged.

Ions are attached to large proteins.

Ions are being moved against their concentration gradient (low to high).

Ions are trapped inside the plasma membrane.

Edit the background in order to illustrate what is happening in the scenario.
YOU MUST LABEL THESE 5 THINGS:
Percentage of WATER inside the mesquite tree leaf. (80%)
Percentage of WATER outside the mesquite tree leaf. (20%)
Put an H where the high concentration of water is.
Put an L where the low concentration of water is.
Draw an arrow to show the direction that the WATER molecules would move.

1

Based on your illustration in Question 3, which way will the WATER molecules move?

Into the mesquite tree leaf.

Out of the mesquite tree leaf.

1

If the mesquite tree leaf was left overnight in the cup, what would happen to the size of the leaf cells?

The leaf cells would increase in size, because water is moving into of them.

The leaf cells would decrease in size, because water is moving into of them.

The leaf cells would increase in size, because water is moving out of them.

The leaf cells would decrease in size, because water is moving out of them.
