Question 9

Biology
1 answer:
Sergeu [11.5K]3 years ago
4 0

Answer:

C₁₂H₂₂O₁₁ + 12O₂  →  12CO₂ + 11H₂O

Explanation:

The last equation is correctly balanced:

C₁₂H₂₂O₁₁ + 12O₂  →  12CO₂ + 11H₂O

There are twelve carbon, 22 hydrogen and 35 oxygen atoms on both side of equation.

All others equations are incorrect because,

C₁₂H₂₂O₁₁ + 12O₂  →  6CO₂ + 11H₂O

In this equation only hydrogen atoms are balanced while oxygen and carbon are not balanced.

2C₁₂H₂₂O₁₁ + 12O₂  →  24CO₂ + 11H₂O

in this equation hydrogen and oxygen atoms are not balanced only number of carbon atoms are balanced.

C₁₂H₂₂O₁₁ + 12O₂  →  12CO₂ + 22H₂O

in this equation hydrogen and oxygen atoms are not balanced only number of carbon atoms are balanced.

Let's suppose you were interested in developing drugs to prevent epigenetic changes that may contribute to cancer. What cellular
Vaselesa [24]

Answer:

Potential targets:

1- DNA methyltransferases

2- Chromatin modifiers such as histone acetyltransferases, histone deacetylases, histone methyltransferases, etc.

3- Components of the RNA interference (RNAi) machinery such as Dicer, Argonaute, etc.

Explanation:

Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.

Answer:

Negative feedback results in the inhibition of an enzyme in a biochemical pathway, reducing the activity of earlier enzymes, and stopping the pathway. Positive feedback results in the activation of more enzymes, thus increasing its production of the product.
