black coffee has a pH of 5, therefore its H+ concentration is ______ times greater than a solution with a pH of 10.
Tju [1.3M]

Answer:

100,000

Explanation:

pH of coffee = 5

pH of solution = 10

Concentration of H+ ions between successive pH values are in multiples of 10

Hence, the pH difference :

pH of solution - pH of coffee

(10 - 5) = 5

Hence, difference in H+ ions will be :

10^5 = 10*10*10*10*10 = 100,000 times

Complete the following vocabulary exercise related to the process of translation of mRNA to protein by the ribosome.Match the wo
vredina [299]

1. The RNA that has an amino acid attached to it, and that binds to the codon on the mRNA, is called a tRNA.

tRNA are molecules involved in protein synthesis (translation) and those molecules connect codons from mRNA with  the amino acids they encode.tRNA has anticodone that binds to mRNA codone.

2. The process, performed by the ribosome, of reading mRNA and synthesizing a protein is called translation.

Translation is a process of gene expression in which proteins are synthesized (translated from the codons on mRNA).

3. Initiation of translation always happens at the start codon of the mRNA.

Translation process can be divided into three stages: initiation (starting off), elongation (adding amino acids to peptide chain that is going to become protein) and termination (finishing up).

4. Amino acids are attached to tRNA by enzymes called aminoacyl-tRNA synthetase.

These enzymes are part of the elongation stage of translation and they catalyze the adding of amino acids.

5. Termination of translation happens when the ribosome hits a stop codon on the mRNA.

Termination is the stage in which the finished polypeptide chain (future protein) is released from the ribosome.

Which of the following statements does not apply to the K value in the equation for the oxygen binding curve of myoglobin? A) It
steposvetlana [31]

Answer:

D) If Y > K, then myoglobin is less than 50% saturated with oxygen.

Explanation:

a regular curve is displayed by myoglobin. when the concentration of oxygen is decreased, the myoglobin will saturate very quickly which means that the myoglobin have very high affinity for the oxygen and dont  easily release oxygen.

so if Y>k, then myoglobin is less than 50% saturated with oxygen.
