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

the decomposition are hydrogen (H2) and oxygen (O2). What is the effect of catalase on the decomposition of hydrogen peroxide? A. It decreases the activation energy needed to start the reaction. B. It decreases the total energy released by the reaction. C. It increases the total energy absorbed by the reaction. D. It changes the ratio of the amounts of the two products.

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.

If parents supplied different alleles for a certain trait to their offspring, What following terms would be used to describe the
My name is Ann [436]
When parents provide a different allele of a given gene, then the offspring is called as heterozygous for that allele.  Alleles turn out phenotypes or physical versions of an attribute that are either dominant or recessive.
The dominance or recessivity related to a specific allele is the result of masking, by that, a dominant phenotype hides a recessive phenotype. By this logic, in heterozygous offspring, solely the dominant phenotype is apparent.

devlian [24]
Based on the diathesis-stress model schizophrenia is the result of interaction between environmental and biological/genetic factors. According to this model, when the combination of the predisposition (diathesis) and the stress (biological, social, and psychological stressors) exceeds a threshold, the person will develop a disorder.

anyanavicka [17]

Answer:

Jake is correct.

Explanation:

Sophie is wrong because although dolphins and sharks can technically be said to be similar, it resulted from convergent evolution, which has nothing to do with common ancestry and rather to do with similar environments for their homes.

Are earthquakes predictable? Explain your answer.
mamaluj [8]

No. Scientists have never predicted a earthquake. We do not know how, and we do not expect to know how any time in the foreseeable future.
