What is the initial velocity of the reaction catalyzed by the wild-type enzyme when the substrate concentration is 10 mM?
Doss [256]

Answer:

50 micro mol/min

Explanation:

So, we have the following parameters which are going to help us in solving this particular Question or problem;

=> For the wild type enzyme, the value for the Maximum velocity = 100 micromol/min.

=> For the mutant type enzyme, the value for the Maximum velocity = 1 micromol/min.

So, we can determine or calculate the value for the initial velocity for each of the enzyme type by using the formula below;

Initial velocity = (substrate concentration × maximum velocity) / substrate concentration + Km.

Therefore, for the wild type enzyme; the Initial velocity = (substrate concentration × maximum velocity) / substrate concentration + Km.

Initial velocity =( 10mM × 100micromol/min) ÷ ( 10mM + 10 mM ) = 50 micro mol/min.

Initial velocity for the wild type enzyme = 50 micro mol/min.

Which of the following is a characteristic of fermented foods?
Kobotan [32]

A vinegar flavor

The fermentation of food is the breakdown of the food molecules, anaerobically.

Explanation:

Usually, anaerobic bacteria or yeast are able to break down molecules like glucose in the absence of oxygen because their main cellular respiration metabolic chain is glycolysis. The pyruvate that is formed at the end of glycolysis is readily converted to lactic acid by the cells before being excreted by the cells. This is why fermented food tastes sour like vinegar. Sourness is a general characteristic of acids.

What is the difference between monotremes marsupials and placental mammals?
vladimir1956 [14]

Here is your answer......

Explanation:

Monotremes are mammals that lay eggs. Monotremes are warm blooded with a fast metabolism. They have hairy bodies to keep warm.

Marsupials are mammals that give birth to live young.  These mammals have a pouch where their young grow and develop. Marsupials are hairy, warm blooded, and produce milk. One of the biggest differences between marsupials and placental mammals is that marsupials give birth quite early and rely less on the nourishment of the placenta. Some examples of marsupials are kangaroo and opossums.

Placental mammals are mammals that give birth to fully developed live young.  They differ from marsupials in that the baby spend more time being nourished in-utero by the placenta. These mammals are hairy and warm blooded as well. Some examples are mice, rats, and bats

The ________ duct empties into the vestibule at the level of the second upper molar.
gavmur [86]

The parotid duct empties into the vestibule at the level of the second upper molar.

Around the back of your lower jaw is where the parotid gland is located. Saliva then passes via a tube known as the parotid duct. The duct's opening is where the saliva spills into your mouth. Different factors might cause the parotid duct to become clogged. The region may swell up as a result of this.

Each gland's front faces a lengthy excretory channel called the parotid duct, which emerges just beneath the masseter muscle. The duct enters the mouth by the buccinator muscle and opens on the inner cheek surface, typically next to the maxillary second tooth
