Describe how the structures of proteins differ from the structures of carbohydrates
Masteriza [31]

Answer:

Both are considered macromolecules. I'll explain below

Explanation:

Proteins are like a huge Lego construction. Each individual piece gets pieced together to make a larger "thing" - Death Star, House, etc. Each individual piece is a monomer, and the larger construction is the polymer. The monomers are Amino Acids and they get pieced together to form the polymer that is called a protein. The linkage that they use is an amide bond, and in biology it is usually called a peptide bond.

Carbohydrates can be singular monomers or polymer units. They are made of completely different compounds - usually aldehydes or ketones. And they link together through different chemical linkages (acetal or ketal linkages for polymers,hemiacetal or hemiketal linkages for monomers).

Both can be large, 3D strucutres - proteins are only functional as a large, 3D structure, while carbohydrates can be singular.

Andreyy89

To choose the strand the promoter acts to aim the RNA polymerase.

<h3>What does RNA polymerase do?</h3>

RNA polymerase synthesizes RNA by following a strand of DNA. The primary transcription enzyme is RNA polymerase. When RNA polymerase connects to a promoter sequence near the start of a gene, transcription starts (directly or through helper proteins). To create a fresh, complementary RNA molecule, RNA polymerase employs one of the DNA strands (the template strand) as a template.

Three distinct RNA polymerases (RNAPs), which transcribe various kinds of genes, are present in all eukaryotes. RNA polymerase I transcribe rRNA genes, RNA polymerase II transcribes mRNA, miRNA, snRNA, and snoRNA genes, and RNA polymerase III transcribes tRNA and 5S rRNA genes.

Energy was added to the molecule. What processes would occur in the cell to add this energy?
lisov135 [29]
In order for energy to be able to be created, ATP(adenosine triphosphate) needs to form in either photosynthesis or krebs cycle from ADP + P(from NADPH). When ATP is available, huge amounts of energy are released when needed by slicing one P atom from ATP So that it can again become ADP and undergo lots of processes to become ATP again. So energy is added from tearing of Phosphate Atom due to tearing of phosphoanhydride bonds. This is possible because of process known as hydrolysis, when ATP is in equilibrium with water and some electrons. And the process of ADP becoming ATP is recharging and occurs in mitochondria.

The processes are hydrolysis and rechargeation, but most important process is Krebs Cycle, where all of this happens.
