Which process connects glycolysis and the citric acid cycle?

[ad_1]

Answer: acetyl-CoA

Explanation:

Glucose plays a central role in energy and carbohydrate metabolism. Glycolysis – Route of degradation of 1 molecule of Glucose in 2 of Pyruvate. Pyruvate can follow 3 paths:

1) Be reduced to Ethanol – Alcoholic fermentation

2) Be reduced to Lactate – Lactic Fermentation

3) Be completely oxidized to CO2 and H2O – Citric Acid Cycle (Performed by animals, vegetables and many microbial cells under aerobic conditions). Glycolysys is linked to the citric acid cycle via the production of acetyl-CoA.

Under aerobic conditions, however, pyruvate is not reduced but rather oxidized in the mitochondria by enzymatic complex pyruvate dehydrogenase (also called pyruvate decarboxylase) with the formation of acetyl-CoA and the release of one molecule of CO2 per every peroxidized pyruvate.

What is the advantage of so many steps in glycolysis?

[ad_1]

Answer:

The correct sequence according to the question is steps- 4→1→3→5→6→2→7.

Explanation:

The given steps show that how the rocks are recycled from one form to another form due to certain factors like weathering over geological time scale which was explained by James Hutton and he termed this concept as the rock cycle.

The steps of the rock cycle in sequence according to the question are:

1.  Breakdown of rock by weathering into regolith- step 4

2.  Dumping and deposition of regolith in a reservoir- step  1

3.  Erosion and transportation of regolith by rain or wind- step  3

4. Cementing of the deposited layer to form sedimentary rock- step  5

5. Conversion of sedimentary rock to a metamorphic rock due to intense heat and pressure- step 6

6. Conversion of  metamorphic rocks to magma due to the melting of metamorphic rocks-
step 2

7. Conversion of magma to igneous rocks due to volcanic activities and cooling of magma-  step 7

Therefore sequence according to the question is steps- 4→1→3→5→6→2→7 is correct.

[ad_1]

The right answer is Transgenic organisms can produce a desired product that may benefit other organisms.

A transgenic organism contains DNA combining  stably integrated in all its cells. In other words, the organism, be it a plant, an animal or a microorganism, has a new piece of DNA embedded in it. a chromosome in each of its cells. This “new piece” of DNA usually contains a gene from another organism (plant, animal or other) that has been modified to be expressed in the new  organization. A transgenic organism may even possess the DNA of another organism of the same species. The inserted gene can be called the transgene.

Currently, diabetics are treated by injecting insulin from either a healthy human donor or cultures of genetically modified (transgenic) bacteria that secrete the protein.

“The diagram shows the inside of a eukaryotic cell. Which process occurs in the structures that are labeled X? lactic acid fermentation alcohol fermentation glycolysis Krebs cycle”

[ad_1]

The diversity of proteins is caused by the mRNA codons and DNA. 
DNA has sequences that mRNA finds the pair for (ex. DNA says AGC, RNA says UCG) 
with that, they only come in 3 nucleotide increments. which is a codon 
one you have a codon, it goes thru tRNA to come out with an amino acid and a bunch of amino acids makes a polypeptide or protein 
It all depends on what the DNA’s code says to make… 
DNA says AUG, RNA makes that UAC which is the amino acid tyrosine 
did I help?

so basically 7

The main difference between respiration and fermentation is that respiration A. requires oxygen. B. uses glycolysis. C. breaks down sugar. D. makes energy.

Answer:

78 g of potassium

Explanation:

According to Lavoisier’s Law, the sum of the mass of the products must be equal to the sum of the mass of the reactants.

On the reaction we have potassium oxide as product (K2O) and as reactants potassium (K) and Oxygen (O2)

Having sayin this, the reaction must be as follows:

K + O2 -> K2O

We need to balance the equation  to have the same amount of molecules of each element in each side:

4K + O2 -> 2K2O

Taking into account the  molar mass of each compound, the reaction can also be written:

4(39g/mol) + 1(32g/mol) -> 2(94g/mol)

solving the  multiplications we have that:

156g of K + 32g of O2 -> 188g of K2O

therefore, we need 78 g of K to obtain 94 g of K2O with 16g of O2
