What is a major difference between facilitated diffusion and active transport?

Biology

siniylev [52]2 years ago

Answer:

The correct answer is Active transport moves substances against the concentration gradient.

Explanation:

The principle difference between active transport and facilitated diffusion is that active transport helps in the movement of various substances in the uphill direction which means against the concentration gradient.

    In simple words active transport helps in the movement of substance from the region of low concentration to a region of high concentration.

On the other hand during facilitated diffusion substances move along their concentration gradient which means from the high concentration region to the region of low concentration until the concentration of both sides become same.

Answer:

To summarize what we know to this point, the cellular process of transcription generates messenger RNA (mRNA), a mobile molecular copy of one or more genes with an alphabet of A, C, G, and uracil (U). Translation of the mRNA template converts nucleotide-based genetic information into a protein product. Protein sequences consist of 20 commonly occurring amino acids; therefore, it can be said that the protein alphabet consists of 20 letters. Each amino acid is defined by a three-nucleotide sequence called the triplet codon

If a plant were to absorb a substance that readily reacts with carbon dioxide in the stroma, the dark reactions would be most li
Assoli18 [71]
The right answer is the dark reaction would stop happening.
The Calvin cycle (or dark reactions, independent of the sunlight) makes it possible to manufacture glucose, an energy molecule, from carbon dioxide. This is called carbon fixation.There are three reactions of this cycle take place in the stroma of chloroplasts: the first of which is the fixation of carbon dioxide. which is a limiting step in this cycle.If a substance other than the components of the dark reactions absorbs and uses carbon dioxide, the carbon cycle will not be able to occur for lack of one of these ingredients which is the CO2.

A standard PCR cycle includes three steps: denaturation (95°C), annealing (55°C), and elongation (65°C).
xz_007 [3.2K]

Answer:

Denaturation process: The DNA template  

Annealing process: Primers  

Elongation process: dNTPs and Taq polymerase

Explanation:

For the denaturing process, the only ingredient that is required is the DNA template that will be separated from a double helix (or double strand) into a single strand, by increasing the temperature to 95 C, (at this temperature the hydrogen bonds that keep together the double stranded break). After the double strand is denatured, the following process is annealing. For this, the required ingredient are the primers; these primers will hybridize or anneal according to the nucleotide complementarity to the single strand of the DNA. Finally, for the Elongation process, you will require the Taq polymerase and the dNTPs. The enzyme will synthesize or “generate” a new strand of DNA based on the DNA template, using the provided dNTPs in the direction 5’ to 3’.

I hope this clarify you inquiry.
