If carbon dioxide levels in the blood increase, the ph will decrease, causing acidosis.
<span>
This happens because carbon dioxide forms carbonic acid, H2CO3 when it is dissolved in water. Carbon acid can lose two H atoms or protons. The loss of protons in a solution is what makes that solution acidic.</span>
True
Amino acids are the basic building blocks of the body. They are also sources of energy, like fats and carbohydrates. However, amino acids<span> are structurally characterised by the fact that they contain nitrogen (N), whereas fats and carbohydrates do not.
</span>
The importance of amino acids as the precursors of enzymes and neurotransmitters<span> is often underestimated. As such, amino acids regulate almost all of the metabolic processes in the human body, and they are essential for a healthy body.</span>
Options for the question have not been give. They are as follows:
A. P site
B. A site
C. E site
D. directly to the cytosol
E. exit tunnel
Answer:
C. E site
Explanation:
Translation is the process by which mRNA is converted into polypeptide chain. Translation machinery has three binding slots for tRNA : A, P and E. Any incoming tRNA encounters A, P and E site in that order.
When a new tRNA (#1) carrying the next amino acid (here, lysine) comes, it enters the A site. Peptide bond is formed between lysine and the already existing amino acid on the growing polypeptide chain on the preceding tRNA (#2). Once lysine is added to the polypeptide chain, the entire chain moves to tRNA #1 which makes tRNA #2 empty. Meanwhile, the machinery moves forward. As a result, tRNA #1 slides to P site and tRNA #2 slides to E site. The A site is empty now and can receive another tRNA.
Answer:
<h2>Only first 1 requires energy, rest all are passive transports!!</h2>
Explanation:
<h3>First one:</h3>
Here the molecules are moving from region of low concentration to high concentration, so as it is an uphill transport also known as Active transport. So active transport requires the ATP to be carried out.
<h3 /><h3>Second one:</h3>
This is the normal passive transport of hydrophobic or lipid soluble substances. So as normal passive transport requires no energy but a concentration gradient. So it doesn't require the ATP to be carried out.
<h3>Third one:</h3>
This is a transport system of protozoans like Amoeba which form a pseudopodia process around the food, and then engulf the substances which then is surrounded by vacoule for digestion to take place. It also doesn't require energy.
<h3>Fourth one:</h3>
This is an example of bulk transport mechanism where large big molecules move from higher concentration to their lower concentration through special membrane proteins and then their utilisation takes place. This is also known as Endocytosis. This also doesn't require energy to be carried out.
