Answer :B. By changing the shape of the enzyme's active site.
check the attachment
Explanation: This is a type of inhibition , in which a molecule binds to another part of the enzyme instead of the active site.
On binding, it disrupts the normal hydrogen bond and hydrophobic interactions holding the enzyme molecule in its three dimensional shape, therefore distorting the conformation and ACTIVE SITE of the enzyme (changed it shape).
Since the active site is the precise location enzyme must bind with substrates for enzymatic reactions,this makes the enzyme not fit for binding with the substrate, therefore the efficiency is reduced. No substrate-enzyme complex, and hence no substrate-product complex for the release of products, this brings down the turnover rate and eventually
<u>the rate of reaction of the enzyme</u>
Thus, the enzyme function is totally blocked, even in high concentration of the substrate,
Mrs. Lopez has the most difficulty initiating digestion of proteins after her stomach is removed. The correct option is C.
Explanation:
When the stomach is removed due to complications such as in cancers the food eaten directly goes to intestine. Without stomach Mrs Lopez will have difficulty in starting the digestion of protein.
The digestion of protein takes place and starts in the stomach and duodenum of intestine. There are enzymes as pepsin, trypsin and chyomtrypsin secreted by stomach and pancreas. Pepsin breaks the peptide bonds of protein.
The HCl and the enzymes in stomach initiates the process of digestion of protein. The amino acids formed are ardent in various metabolic processes and repair.
lipids and carbohydrate digestion starts from the mouth only as salivary amylase and lipase initiates the process.
Answer:
We determined that if phosphorus is provided at the required level of 0.33%, the optimal ratio of calcium to phosphorus is 1.39:1 or 1.25:1 to maximise daily gain and gain-to-feed, respectively. To optimise bone ash, which is important for breeding sows, the ratio is 1.66:1,”
Explanation:
Four critters that are pollinators are
- Bumblebee
- Honeybee
- Rufous Hummingbird
- Flower fly
