Normally, in the process of osmosis, the net flow of water molecules into or out of the cell depends upon differences in the

  1. concentration of water molecules inside and outside the cell

  2. concentration of enzymes on either side of the cell membrane

  3. rate of molecular motion on either side of the cell membrane

  4. rate of movement of insoluble molecules inside the cell

Answer choice 4 is incorrect because _____________________________________________________________

Sodium ions are "pumped" from a region of lower concentration to a region of higher concentration in the nerve cells of humans. This process is an example of

  1. diffusion

  2. passive transport

  3. osmosis

  4. active transport

Answer choice 3 is incorrect because _____________________________________________________________

Let's warm up our minds. Answer the following questions based on the AIM without using internet resources.

 

Aim: How do cells benefit from an exchange of substances in and out the cell?

  1. Why is it important to exchange substances in and out the cell?

  2. How do cells use the substances that enter the cell?

  3. How can a cell survive if it doesn’t exchange the substances it needs?

 

The following video discusses Cellular Respiration. This biochemical process occurs in both Plant and Animal Cells.

Log onto BrainPop and watch the Cellular Respiration video.

Answer the following questions to complete your notes on Cellular Respiration.

  1. What is cellular respiration?

  2. What substances are necessary for cellular respiration?

  3. What are the end products of cellular respiration?

  4. How does the mitochondria carry out the process of respiration?

  5. How does respiration occur if there isn’t enough oxygen?

  6. Using EVIDENCE from the video provide an ANALYSIS for the AIM. (How do cells benefit from an exchange of substances in and out the cell?)

As scientist, part of your job is to do research on experiments that have been conducted already based on your topic of interest. You are to research and write a mini-proposal describing how you would invesigate the factors that affect cellular respiration. Create a presentation that shows how you would investigate factors that affect cellular respiration.  In your presentation include the following:

  • Identify the variables of the experiment you would conduct? Independent variable, dependent variable, constants

  • Summarize the procedures you would take to conduct this experiment? (How would it work? What would you do?)

  • Hypothesize the effects of the variables in this experiment. (if… then…)

 

Here is a template of what your pesentation should look like using google presntations. [Click template for access].  You are not limited to the use of google presentation. You can use Prezi or any other presentation app to present your ideas.

 

Use the following search prompts to find information:

  • experiments on cellular respiration

  • cellular respiration labs 

  • cellular respiration investigation

 

Lastly, You must create 3 questions that your peers should be able to answer based on your presentation. Include the answers to your questions. Fill out this FORM to submit your questions and answers.

 

You will be required to present your research to your classmates. You can create a video of your presentation and submit it! Use these links to record your video:

Answer the following questions:

  1. How does a lack of oxygen affect cellular respiration?

  2. How does a lack of sugar or food affect cellular respiration?

  3. What can be done to get cells to release more waste products

     like carbon dioxide and water?

                                              You will need several materials to complete today's activity. Take a                                                 look at the worksheet to identify all the materials needed for this                                                   lesson. You can conduct this experiment at home or in your                                                         classroom. You may need to substitute test tubes for plastic bottles                                                 if you do not have this item. All other items you should be able to                                                 find in your local grocery store/ and arts and crafts store.

 

 

 

 

 

Today you will conduct an experiment determining factors that affect cellular respiration. It maybe possible that your presentation is this same experiment.  Follow the directions on the worksheet to investigate the effects of sucrose on cellular respiration.  You will:

  • Hypothesize the effects of sucrose on cellular respiration

  • Conduct a controlled experiment

  • Collect data

  • Analyze your data to come to conclusions

Boss Level

 

Using your data tables from the cellular respiration mini-lab create two different but appropriate representations of your data in the form of graphs. You can create the graphs by hand or on google sheets. Include titles, appropriate scales, and correctly plotted data. Your graphs must be NEAT!
