HS-LS1-3 Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.

Learning Goals (I can...):

1. Explain how concentration gradients and membrane permeability affect the rate of transport.

2. provide examples of pumps and other membrane structures that are used in active transport.

3. provide a short list of similarities and differences between active and passive transport.

In the next section, you will watch a video related to active transport.

As you watch, think about the following questions:

What do you think is occurring?
What part of the cell is involved?
What is needed in order for the observed process to occur?

Briefly explain what you think happened in the video.
(I have to grade this, manually)

What happened?

In the video, you saw an example of how the immune system works to destroy foreign cells and substances.

The large cell in the center was a human macrophage, a part of the immune system. The little cells shaped like donuts were red blood cells from a sheep. The human macrophage engulfed the sheep blood cells because it did not recognize them (remember the glycoproteins and glycolipids are used to identify the cell) and attacked them as invading or foreign cells. When cells engulf material such as other cells or invading bacteria, this is a form of active transport.

Use the information from the video to help you match the vocabulary terms to their definition.

Draggable item		Corresponding Item
exocytosis		used when molecules pass through the cell membrane against the concentration gradient with the use of ATP
protein pump		occurs when a vesicle merges with the cell membrane to bring material into the cell
passive transport		occurs when a vesicle merges with the cell membrane to release material from the cell
endocytosis		the movement of molecules across a cell membrane using ATP
active transport		movement of molecules across a cell membrane without the use of ATP

Next, watch the video below that will discuss the protein pump. As you watch the video, watch for the role of ATP and the presence of a concentration gradient and its role in this process.

A protein pump is located in the .

Mmuae Afoforo a Wobɛpaw:

mitochondria

cell membrane

cytoplasm

centriole

2

Why does sodium and potassium ions need a protein pump to pass through the cell membrane (select all that apply)?

The ions are moving against the concentration gradient.

The ions have a charge and cannot pass directly through the cell membrane.

ATP is not essential with either type of transport through the cell membrane.

Energy is needed to move the ions.

2

Molecules moving against the concentration gradient move from an area of to and area of .

Mmuae Afoforo a Wobɛpaw:

high concentration to low concentration

low concentration to high concentration

low concentration

equal concentration

high concentration

1

Protein pumps are efficient because they...(select all that apply)

use energy

can move two types of molecules

can only move one type of molecule

use diffusion

Watch the video below. As you watch, pay attention to the following, pause the video when you hear it, and record the information where it asks for it below the video:
