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

additional required readings

practice test questions

review questions

relevant microbiology photos

links to additional educational resources

LEARNING OBJECTIVES

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

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

LECTURE POWERPOINT

Versions of Microbial Metabolism & Growth PPT:

Student's Microbial Metabolism & Growth PowerPoint Show

Student's Microbial Metabolism & Growth PowerPoint PDF Printout

Fill-in-the-Blank Format:

All of the lecture PowerPoints used in the Virtual Cell Biology Classroom are fill-in-the-blank format to encourage students to pay attention and follow along during the presentation.

Printing:

The best way for students to print out the PowerPoint Show is to download the PDF version. Select Print, and, when the Print screen comes up, go to the Print Handling options. Under Page Scaling, select "Multiple pages per sheet", Under Pages per sheet, select "2". That uses up less paper, placing two slides on each page.

DIFFERENTIAL MEDIA & MICROBIAL METABOLISM HOMEWORK ASSIGNMENT

This assignment will help reinforce your understanding of the relationship between differential media and microbial metabolism. This same assignment is featured under the Microbial Metabolism and Microbial Growth & Metabolism lectures.

REQUIRED READINGS

Here is what you need to read, in addition to the PowerPoint, to master this topic. Check Moodle & your textbook for additional readings.

Why Do We Breathe? Aerobic Cellular Respiration

Cellular Metabolism: What Is Fermentation?
