So, what's the deal with Active Transport?

Recall that passive transport doesn't use energy because it's going with the flow, down the concentration gradient, from high concentration to low concentration.

Active transport is quite literally the opposite. Active transport requires the cell to use energy to go AGAINST the concentration gradient, forcing molecules to go from low concentration to high concentration.

Where does cellular respiration take place?

Multiple Choice

Which of the following is TRUE?

• Only animals undergo cellular respiration.

• Only plants undergo cellular respiration.

• Both plants and animals undergo cellular respiration.

• Neither plants nor animals undergo cellular respiration.

Multiple Choice

Why is cellular respiration important to living organisms?

• It produces glucose.

• It forms carbon dioxide.

• It makes oxygen.

• It makes energy (ATP).

So, what's the deal with Active Transport?

Life needs energy to do work and perform necessary functions. The energy that is used by cells for active transport (and other life functions) is supplied by a molecule called ATP.

ATP stands for Adenosine Triphosphate.

We'll talk more about ATP later. This is all you need to know for now :)

How do molecules move during Active Transport?

Active transport of molecules is carried out by Protein Pumps embedded in the cell membrane.

Protein pumps are fueled with ATP to allow certain molecules and ions to pass only one direction, into the cell. This allows cells to “stockpile” certain substances in far greater concentrations than they occur outside the cell. The ATP is used to:
1. Change the shape of the pump protein during operation
2. Move molecules through the pump from low to high concentration.

Multiple Choice

Which of the following is NOT a type of passive transport?

• Osmosis
• Diffusion

How do molecules move during Active Transport?

There are a few kinds of active transport, but you only need to know these two:




1. Endocytosis




2. Exocytosis

Drag these tiles and drop them in the correct blank above

Endocytosis

Exocytosis

How does ENdocytosis work?

Some particles enter a cell without actually crossing the membrane.

The cell will create a pocket/sac of membrane around a resource it wants/needs. This pocket is called a vesicle (sounds like vehicle).

This process of bringing particles into a cell using extensions of the membrane is called endocytosis. The material taken in can either be solid or liquid.

Depending on the materials being taken in by the cell, we call endocytosis one of two things:

Phagocytosis (Cell Eating)

Pinocytosis (Cell Drinking)

Multiple Select

Which of the following statements about endocytosis are correct?

• It involves the cell membrane surrounding particles.

• It can bring in both solid and liquid materials.

• It forms a vesicle around the particles.

• It only occurs with solid particles.

How does EXocytosis work?

The reverse process of releasing materials (like waste, or purposeful cell secretions) from the cell to the outside is called exocytosis.

Exocytosis requires a vesicle containing substances to be released fusing with the cell membrane, expelling its contents to the environment outside the cell.

For example, this process is used by the cell to get rid of materials that could not be digested (by the actions of enzymes found in the lysosome).

Exocytosis is therefore a form of egestion

What are some EXocytosis examples?

Another example of exocytosis occurs when proteins made by a cell are released or “exported” for use elsewhere in the organism. These proteins are referred to as secretions.

Examples of include: digestive enzymes, mucus, saliva, tears, and venom.

Endocytosis

Multiple Choice
