Several general characteristics of metabolic reactions or reaction pathways are listed below. sort them into the appropriate metabolic category (anabolism, catabolism). a. convert small compounds to larger compounds b. generally endergonic (nonspontaneous) c. convert nad* to nadh d. produce atp e. convert nadph to nadp* f. convert large compounds to smaller compounds

Anabolism includes three basic stages. First, the production of precursors such as amino acids, monosaccharides, and nucleotides. Second, is the activation of these compounds into a reactive form using energy from ATP. Third, combining these precursors into complex molecules, such as proteins, polysaccharides, fats, and nucleic acids.

In the catabolism reaction, it will simplify the form of proteins into amino acids. Then this amino acid is oxidized to urea and carbon dioxide. This reaction produces energy. In addition to breaking down proteins, catabolism can also break down complex carbohydrates (polysaccharides) into simple carbohydrates (glucose, fructose, and ribose). This simple carbohydrate will be broken down again through a reaction called glycolysis. From this reaction, energy is produced.

Anabolism is a process that is part of metabolism that occurs in a series of chemical reactions in the form of the preparation of complex substances from simple substances. In other words, the process of anabolism is a chemical process in the form of the preparation of simple substances into more complex substances.

Anabolism that uses light energy is known as photosynthesis, while anabolism that uses chemical energy is known as chemosynthesis.

Catabolism is a chemical process that occurs in organisms in the form of the breakdown of complex molecules/substances into simpler molecules/substances. Catabolism is the opposite of the process of anabolism.

Catabolism is a metabolic pathway that reshapes a complex substrate of organic molecules into its constituent components while releasing energy, generally in the form of ATP. In the catabolism pathway, large molecules such as polysaccharides, lipids, nucleic acids, and proteins will be chipped into smaller molecules such as monosaccharides, fatty acids, nucleotides, and amino acids.

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
