Summary Introduction
To determine:
Use of urease for Helicobacter pylori.
Introduction:
Urease is an enzyme that helps in the hydrolysis of urea, leading to the formation of ammonia and carbon dioxide. Urease rich seeds are soybeans, plant seeds, and jack beans. It also found in various organisms and is also secreted by intestinal microbes.

Clostridium tetani is a common soil bacterium and causes tetanus. Would you expect C. tetani to possess the enzyme catalase? Explain.
Chlamydia are pathogenic bacteria that must be grown within a eukaryotic host cell. They rely on the host cell for many nutrients, including nucleotides, lipids, and amino acids. It is thus no surprise that when grown in co-culture with a host depleted of any of these metabolites, chlamydial growth declines. However, high levels of certain amino acids also inhibit chlamydial growth. Specifically, the amino acids leucine, isoleucine, methionine, and phenylalanine slow down the growth by inhibiting the amino acid transporter called BrnQ. On the other hand, if valine is present in the medium these amino acids have no effect on BrnQ. Discuss how this might be possible
