<span>Certainly. Every organism has a variety of different characteristics. One person writing a key might choose to use different characteristics than another person would use.
For example: Here's a key for separating fish, snake, frog and mouse
1.
A. Has scales on its skin ... 2
B. Has no scales on its skin ... 3
2.
A. Breathes with gills - fish
B. Breathes with lungs - snake
3.
A. Has hair or fur - mouse
B. Has no hair or fur - frog
Here's a different key for the same four animals:
1.
A. Has four legs ... 2
B. Does not have 4 legs ... 3
2.
A. is warm-blooded - mouse
B. is cold-blooded - frog
3.
A. has fins - fish
B. has no fins - snake</span>
Do not worry so much about the why of classification. Classification is important because it is a lens through which to see what is there. It is not intrinsically true in and of itself. Distinctions are important only as vehicles for a common base of communication. All things have symmetry. A reflection has symmetry. Symmetry means organized life. Organized life is what happens when RNA replicates. It is the difference between chaos and order
Answer:
<h3>Enzymes are typically which type of biomolecule?</h3>
Enzymes are protein biomolecules.
Enzymes are bound to specific substrate/s and act as <u>catalysts</u> that makes chemical reactions faster, such as breaking down lactose to smaller units of glucose, which is accomplished by lactase.
<u>Cofactors (metal ions such as iron, zinc) and coenzymes (organic molecules like vitamins)</u> may be needed to initiate chemical reactions.
<h3>Describe the effects that enzymes can have on substrates.</h3>
After creating the <u>enzyme-substrate complex</u> through <u>induced fit</u>, enzymatic products are seen after the reaction. The <u>substrates may be consumed during the process or preserved</u> to be used again.
For example, these enzymatic products may be used for feedback inhibition to control the chemical reaction and production of a certain hormone.
