Answer:
Ethics can be described as a set of moral rules which are necessary to distinguish between the right and wrong. Ethics is very necessary for science as the field of science especially scientific research would become deadly if ethics are not followed. If ethics are not followed, scientists will begin killing of organisms and humans to support science projects. Human cloning will become a non- serious matter in ethics are not followed. Hence, commitment to ethics is very important in science.
Answer:
Enzymes' shapes are important because it determines the specific substrate it will act onto.
Explanation:
The shape of the enzymes are explained by two theories, which are Lock and Key Theory and Induced Fit Theory.
<h3>Lock and Key Theory </h3>
This was first coined by <em>Emil Fischer in 1894</em>. Just like how a key has a specific keyhole, <u>enzymes' active sites are supposed to act on specific substrates to produce a catalyzed effect</u>. Incorrectly shaped keys or enzymes will not fit into a lock (substrate) not assigned for it.
<h3>
Induced Fit Theory</h3>
this theory was proposed for the substrates that do not qualify for the Lock-and-Key theory, or <u>enzymes that have more than one active sites</u>. It is said that the <u>substrate determines the final shape of the enzyme</u>, and that the<u> enzyme is somehow pliable</u>. The enzyme is then modified by the substrate to form an enzyme-substrate complex. This explains why two or more enzymes can catalyze a single substrate.
<h3>Additional notes:</h3>
For enzymes to work, they may need specific molecules.
A coenzyme may be <u>metal ions (iron, copper, magnesium)</u> or <u>organic molecules (Vitamins B2, B3, B8)</u> which attach to an enzyme to form a holoenzyme. An apoenzyme is an enzyme with only its protein part sans the cofactor.
Predisposed mean increased the risk of developing cancer. In most case, it doesn't mean that you will 100% develop cancer but your chance will be much higher than other people.
That risk also can be increased if you doing risky behavior like sunbathing. Again, that doesn't mean you automatically get cancer someday.
<span>In order to understand trans fat, you must understand the prefix. Trans and cis are prefixes that mean opposite and same side, just like transgender people identify with a gender that is not in line with their biological sex, and cisgender people identify with their biological gender. Cis fat describes the fatty acids attached to the glycerol in triglycerides. Cis fats have hydrogen attached to the carbon chain just like trans fats, but at one, two, or more places on the chain, two hydrogen atoms attached on the same side, and the fatty acid chain gets bent, making the collection of fats less dense and therefore healthier for you and I. Trans fats have hydrogen atoms on alternating sides all the way down the chain, making them denser and solid at room temperature. In order to turn a plant oil (cis fat) into trans fat, the cis fat has to be blasted with hydrogen in order to turn the fatty acid chains from cis to trans. This adds more energy to the fats while also making them denser, which turns olive oil into a butter-like substance.</span><span />
