Myristoyl-CoA is a saturated fatty acid with 14 carbons attached to coenzyme A. How many molecules of ATP would be generated fro
sladkih [1.3K]

Answer:

Total ATP molecules produced = 94 molecules of ATP

Explanation:

Myristoyl-CoA, is a saturated fatty acid with 14 carbons which has been activated for oxidation by attachment to coenzyme A. When it has undergone complete oxidation, it will yield 7 acetyl-CoA molecules and 6 FADH₂ and 6 NADH molecules each.

Each of the 7 acetyl-CoA molecules obtained from its initial oxidation enters into the citric acid cycle and is completely oxidized to yield further ATP and  FADH₂ and NADH molecules.

The overall yield of ATP from the various enzymatic steps is shown below:

Acyl-CoA dehydrodenase = 6 FADH₂

β-Hydroxyacyl-CoA dehydrogenase = 6 NADH

Isocitrate dehydrogenase = 7 NADH

α-Ketoglutarate dehydrogenase = 7 NADH  

Succinyl-CoA synthase = 7 ATP (from substrate-level phosphorylation)  

Succinate dehydrogenase = 7 FADH₂

Malate dehydrogenase = 7 NADH

Note: 1 FADH2 molecule yields 1.5 ATP; 1 NADH molecule yields 2.5 ATP molecules. Therefore,

Total ATP  from FADH₂ molecules = 13 * 1.5 = 19.5  

Total NADH molecules = 27 * 2.5 = 67.5

Total ATP molecules produced = 19.5 + 67.5 + 7  = 94

Total ATP molecules produced = 94 molecules of ATP

We covered transcription and translation in our lab this week. Below, you'll find several steps required for protein synthesis.
AlladinOne [14]

Answer:

The correct answer is :

  • The 2 strands of DNA separate
  • mRNA is built based on the DNA template
  • mRNA leaves the nucleus
  • tRNA brings an amino acid into the P site.
  • tRNA brings an amino acid into the A site.
  • tRNA leaves the P site and a peptide bond is formed between the amino acids.
  • The mRNA+attached tRNA shifts, moving the 6-tRNA from A site to the P site.
  • The entire mRNA strand is translated into amino acids and a polypeptide is formed.

Explanation:

Protein synthesis is a process that is made up of two distinct processes namely transcription and translation.

Transcription: this process include several steps where the segment of DNA which has information, copied into the new molecule called mRNA which acts as the template as it has information copied from the DNA to produce gene expression.

Translation: is the process includes several steps in which a peptide chain is formed from the mRNA with the help of tRNA and ribosomes.

The correct order of steps is given under the answer heading.

What landform develops on coral reefs as a result of wave action
Talja [164]
A reef is a ridge of a rock of any type of land that extends some distance just under the surface of the water. A coral reef is a lot of calcium carbonate that is also made up of living creatures. A coral reef is created when a small amount of dead coral turns into calcium carbonate. This process is very slow. The famous reefs are the Great barrier Reef of Austria and Belize and Cayman Islands.
Wave actions are usually not a problem due to hard coral reefs. The reef reduces a wave energy. But sometimes waves can break off or flatten large portions of coral reefs, forming grooves in once circular reef. The higher areas between the grooves are known as buttresses and may grow together at the top producing arches. 
Answer:  Landform that develops on coral reefs as a result of wave action are Arches.
