Enzymes catalyze chemical reactions in the human body. Which statement best describes how enzymes work?
A They speed up chemical reactions by increasing the activation energy.
B They slow down chemical reactions by increasing the activation energy.
C They speed up chemical reactions by lowering the activation energy.
D They slow down chemical reactions by lowering the activation energy.
Answers
Answer:
A
Explanation:
Hope this is helpful!!:)
Enzymes work by speeding up chemical reactions through the lowering of the activation energy of the reactants.
In every reaction, reactants need to summon a minimum energy amount before they can get to products. this energy is referred to as activation energy.
When an enzyme is introduced into a reaction, it lowers the activation energy. By doing so, reactants can get to products quicker because the mountain they need to climb has been lowered by the enzyme.
In other words, enzymes create a shorter route for reactants to take towards their destination - products.

D.carbon dioxide
Answers
Answer:
B.Sugar ( Glucose)
Explanation:
I hope this helps!
A compound that is formed as a common product of the process of photosynthesis is sugar (glucose).
What do you mean by Photosynthesis?Photosynthesis may be defined as a process through which plants utilize carbon dioxide and convert it into glucose in the presence of sunlight.
The reactants of photosynthesis are carbon dioxide and water, while the products are glucose and oxygen.
The reaction of photosynthesis is given below:
[tex]6CO_2 + 12H_2O[/tex] → [tex]C_6H_1_2O_6 + 6O_2 + 6H_2O[/tex]
Therefore, a compound that is formed as a common product of the process of photosynthesis is sugar (glucose).

why is there is no point in adding more generations when an allele has become fixed
Answers
Answer:
Low genetic diversity, which is seen with allele fixation, is dangerous as it can lead to mass extinctions. If there is little genetic variability within a population and the genetically similar individuals all are susceptible to a certain pathogen, the population will likely cease to exist. This is why we see examples of populations with fixed alleles becoming threatened or endangered

a. insertion of RNA primer sequences
b. sealing the gaps between fragments
c. opening multiple origins of replication
d. proofreading new DNA strands
Answers
Answer:
D
Explanation:
Key points:
- Cells have a variety of mechanisms to prevent mutations, or permanent changes in DNA sequence.
- During DNA synthesis, most DNA polymerases "check their work," fixing the majority of mispaired bases in a process called proofreading.
- Immediately after DNA synthesis, any remaining mispaired bases can be detected and replaced in a process called mismatch repair.
- If DNA gets damaged, it can be repaired by various mechanisms, including chemical reversal, excision repair, and double-stranded break repair.
