Summary Introduction
To review:
The property of an enzyme in general, which enables luciferase to attach only to luciferin molecule. Also, explain catalysis by luciferase taking this enzymatic property into consideration.
Introduction:
The fireflies show the phenomenon of bioluminescence with the help of luciferin, which is present in their abdomen in an organ known as a lantern. This reaction takes place in the presence of an enzyme luciferase, which behaves as a catalyst.
The enzyme luciferase undergoes a change in the shape when it binds to luciferin and adenosine triphosphate (ATP). This prevents the attachment of the water molecule at the active site of the enzyme.

In a population of Jackalopes (pictured below), horn length will vary between
0.5 and 2 feet, with the mean length somewhere around 1.05 feet. You pick
Jackalopes that have horn lengths around 1.75 feet to breed as this appears to
be the optimal length for battling other Jackalopes for food. After a round of
breeding, you measure the offsprings' mean horn length is 1.67. What is the
heritability of horns length (h2)? Is Jackalope horn length a heritable trait? (4
pts)?

Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a load of x50,000 bacteria/gram is considered unsafe. Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar. The following colony counts are measured: Time (days) MicroYo colony count# 1 1 4 1 12 2 16 20 4 7 What day should you recommend expiring the yogurt (the last possible date before the microbial load is unsafe). 12 4 20 16arrow_forward
