Q1. While plotting the growth curve for the Vibrio culture it is critical to calculate the linear regression only throughout the log-growth phase of the culture. How would the value of k change if the lag and stationary phases were included? Why would the length lag phase be different from […]

1. The recipe for 10x TBE buffer is 890 mM Tris, 890 mM boric acid, 20 mM EDTA. What is the concentration of 1x TBE buffer? 2. A recipe calls for 10 ml of a 25mM stock of EDTA. However, all you have on hand is a 500 mM stock. […]

Describe three ways in which enzyme activity levels in a cell can be regulated. Include at least one example inwhich the substrate itself is involved in regulation, and at leastone in which a non-substrate molecule is involved. For asubstrate/enzyme interaction, describe the induced fit model ofenzyme activity. For a non-substrate/enzyme […]

A huge amount of water–7 to 9 L–moves from the blood into the bowel every day, through osmosis and digestive secretions. Since people only have 5 L of blood, why don’t they die from losing all the water from their blood into the bowel? What will the water do then? […]
