Microbial Metabolism & Growth Lecture Materials

These are the Microbial Metabolism & Growth Lecture materials of the Virtual Microbiology Classroom. The resources below are used to supplement an actual college microbiology course. Anyone taking, teaching or interested in biology may find these materials helpful and is welcome to use them.

The Microbial Metabolism & Growth Lecture materials include:

a list of learning objectives

a PowerPoint lecture

a homework assignment

"class note" articles

practice test questions

review questions

relevant microbiology photos

links to additional educational resources

MICROBIAL METABOLISM & GROWTH LECTURE LEARNING OBJECTIVES

These lecture learning objectives are a study guide based on the VMC Microbial Metabolism & Growth Lecture PowerPoint:

Understand difference between catabolism / anabolism and what these reactions have to do with metabolism.

Understand what a redox reaction is and what this type of reaction has to do with metabolism.

Understand the steps of aerobic cellular respiration to the detail that we discussed in class (starting molecule, end product molecule, what is produced in each pathway or subpathway. You do not need to know the name of every molecule at every substage of these processes).

Understand how aerobic respiration, anaerobic respiration and fermentation differ.

Understand how metabolism relates to the differential aspect of MacConkey's and Mannitol Salt specialized media.

Explain what “microbial growth” means.

Know the 4 phases of the microbial growth curve.

Understand how microorganisms are grouped based on their relationship with oxygen, temperature, pH & osmotic pressure.

How does bacterial generation time relate to characteristics of disease? (Another “think” question.)

Understand what it means for binary fission to result in exponential growth.

Understand the different factors that affect bacterial growth and how they influence the speed of population growth. Know any terminology associated with these factors.

Know the microbes that we met in this lecture and their relevance to the topics discussed.

- Mycobacterium leprae and Generation time

- Listeria monocytogenes and Temperature

- Helicobacter pylori: pH & Oxygen

- Campylobacter jejuni and Oxygen

- Staphylococcus epidermidis and Osmotic Pressure

MICROBIAL METABOLISM & GROWTH LECTURE POWERPOINT

All of the lecture PowerPoints used in the Virtual Microbiology Classroom have fill-in-the-blanks on many of the slides to encourage students to pay attention and follow along during the presentation. Instructors, contact us for the information that goes in the blanks.

HELPFUL TIPS: Some of the PowerPoint presentations are large files and may take a few moments to download, depending on the speed of your internet connection. If you are printing a hard copy of the PowerPoint, you can save paper by selecting Handouts (rather than Slides) in the "Print What:" drop down menu of the PPT print screen. Then you can choose the number of slides you want to have on each printed page. If the printed PPT presentation is to be used as student notes, it is best to choose handouts with 2 or 3 slides per page.

MICROBIAL METABOLISM & GROWTH HOMEWORK

Word document of a single essay question given to students at the end of lecture. This tool helps the students review the main messages of the lecture while allowing the instructor to assess the class' understanding of the material.

MICROBIAL METABOLISM & GROWTH CLASS NOTES

Here are brief summaries of some of the various subtopics and concepts introduced in this lecture, kind of like really good class notes.

Cellular Metabolism: What Is Fermentation?

What Is the Nucleotide Adenosine Triphosphate (ATP)?

What Is the pH Scale? Measurement of Acidity & Alkalinity
