Many cells make and use an enzyme, called catalase, to facilitate the decomposition of hydrogen peroxide (H2O2). The products of

Len [333]

Answer:

A. It decreases the activation energy needed to start the reaction

Explanation:

Organic catalyst which speed up the rate of organic chemical reaction is living cells are called enzymes.They have specific reaction site called active sites.This must be in prefect shape with the substrate for the organic chemical reaction to take place

When this occurs the minimum amount of energy of reaction to activate or stimulate the the atoms and molecules of the substrate to undergo chemical reaction is lowered.This energy of reaction is celled activation energy.

Catalase thought its active sites lowers the activation energy so that the molecules of H2O2 could break down to C02 and H2 faster,thereby reducing the time for theses product to form.The is the general roles of enzyme.To increase the rate of chemical reaction,by reducing the activation energy.

Nady [450]

Answer:

Valine-Leucine-Proline-Lysine-Histidine

Explanation:

The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.

N.B: Thymine is replaced by Uracil in the mRNA

For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU

Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)

Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).

GUG specifies Valine amino acid

CUG specifies Leucine amino acid

CCU specifies Proline amino acid

AAG specifies Lysine amino acid

CAU specifies Histidine amino acid
