What is true if enzymes

Answers

Answer 1

Answer:

Answer:

Option (2).

Explanation:

Enzymes are made of proteins that have the specific amino acid sequences. Enzymes have well determined 3D shape and work in their specific shape and at specific physical and chemical condition.

Enzymes may acts as catalyst that can increase the rate of the bio chemical reaction. Each enzyme is specific for one reaction and lowers the activation energy of the reaction. Enzymes increases the effective collision between the substrate molecule and increases reaction rate.

Thus, the correct answer is option (2).

Answer 2

Answer: I may be wrong but I think it’s the second one. They speed up reactions, and there’s a certain enzyme for a certain reaction.

Read the blog entry below and answer the question that follows:At first I dreaded going to sixth grade camp. I was sure the food would be poisonous, I would freeze to death in my sleeping bag, and the other kids in my cabin would never talk to me. But was I wrong! In fact, it was the best week ever! I went horseback riding and participated in a ropes activity with a zip line course. After the course, I climbed to the top of a pole using only ropes and carabiner clips, and then I rappelled off the top. I even made a new best friend. Oh, by the way, the food was delicious. It tasted better than my mom's! (But don't tell her.)

Review the first sentence:

At first I dreaded going to sixth grade camp.

What is the connotation showing here?

The author was impatient and could not wait to get to camp.
The author was worried he/she might not enjoy camp.
The author welcomed the opportunity to go to camp.
The author was excited about going to camp.

Answers

The answer would be B. The author was worried he/she might not enjoy camp.

He/She wasn't impatient because it said she "dreaded" it so that rules out A.
He/She wasn't welcoming the opportunity, because again, the word "dreaded" was used.
He/She wasn't excited because "dreaded" does not imply excitement.

I think it's B. The author was worried he/she might not enjoy camp.

Because anyway I was just scrolling through the questions and I was just like I know this question I just did it a few days ago! So this is pretty much a verified answer! :)

2. How does the structure of an enzyme affect its function?

Answers

Explanation:

Enzymes. Most enzymes are proteins and therefore their function is specific to their structure. ... The enzyme binds with the appropriate substrate only in the correct alignment and orientation to connect the molecules. The resulting enzyme-substrate complex enables the reaction to occur.

What makes the tea with milk and lemon curdle?

Answers

Answer:

The tea with milk and lemon curdles due to the acidic nature of lemon.

Explanation:

Milk is made up of a number of proteins like casein. The proteins in milk are denatured by the addition of lemon juice. When lemon juice is added to tea or milk, the proteins such as the negatively charged casein become neutralized. Now, as no negative charge is present on them so they start to crumple together rather then pushing each other apart. Hence, the clumping causes the milk to curdle in tea.

Answer:

because of the acidic nature of the lemon
