Which of the following would occur if cells did not have enzymes?

a, cells would not have any chemical reactions taking place.
b. cells would have some chemical reactions, but not enough to support life processes.
c. reactions in cells would be too slow to sustain life.
d. reactions in cells would be prevented from producing needed products at the right time.

which of the following would differ if you compared the same reaction taking place with and without an enzyme?

a. the chemical energy of the reactants
b. the chemical energy of the products
c. the energy required to start the reaction
d. the overall energy of the reaction

The correct answers are - 1. option C. and 2. option C.

Explanation:

Enzymes are the bio-molecule that catalyze the biochemical process by lowering its activation energy. It plays a critical function in lower the activation energy of the reaction inside the cell. Almost all the reaction occurs inside the cell are too slow at normal temperature.

The enzymes help in speeding up the cellular biochemicals reaction. Enzyme does this by binding to substrate molecule so it would be easy to bond breaking and forming.

Thus, the correct answers are -  1. option C. and 2. option C.

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.

the backbone of the dna and rna compound is sugar phosphate.
