During chemical reactions, the chemical bonds between atoms are altered. ... Enzymes make chemical reactions take less time by decreasing the activation energy of the chemical reaction. The role of the enzyme-substrate complex is to provide the energy to break or form bonds in chemical bonds.

Following the rules of complementary base pairing, which of these DNA bases could successfully bond with adenine?
AURORKA [14]

Answer:

Thymine

Explanation:

Adenine is a Purines together with Guanine .

Purines always pair with Pyrimidines ; which are cyosine and Thymine.

This is a complementary base pairing that hold the two strands of DNA bases together by weak hydrogen bonds for flexibility and easily unwind during replication

Purines are larger in size beaxuae they have 2 ring structures while Pyrimidines aee smaller because of one ring structure.

Therefore two purines (Adenine and Guanine can not pair together;

It must be a Purines -Pyrimidines pairs.

Therefore Adenine must pair with Thymine and cyosine with Guanine

In RNA, Thymine are replaced with URACIL as Pyrimidines.

During a laboratory experiment, you discover that an enzyme-catalyzed reaction has a G of -20 kcal/mol. If you double the amount
luda_lava [24]

Answer:

-20 kcal/mol (It stays the same)

Explanation:

Enzymes will reduce the Gibbs free energy of activation, but will neither increase or decrease the free energy of reaction.

Enzymes means of activity is by decreasing the activation energy (Ea or ΔG✳) for a reaction. This in turn raises the reaction rate.

Free energy of reaction

= free energy of product - free energy of substrate

The free energy of the product remains constant even without the enzyme. Hence, the enzyme would show no effect on the free energy of the reaction.

The attached image shows the effect of changes in enzyme concentration on the free energy.

The critical difference between today's global warming and Earth's previous climate changes is that
matrenka [14]
<span>previous changes in climate were dramatic but very short-lived.

</span>
<span>The issue of whether human activities cause global climate change is indeed a controversial topic. The limitation to climate research that could be overcome through scientific design is "Data from a wide range of time periods must be analyzed." Very powerful, or Super Computers, are required to analyze large amounts of data. The sooner more powerful computers are developed, the sooner data from the wide range of time periods can be analyzed. This will give scientists a better idea of the extent of global warming, if any, and how to prevent it.
