Answer:
When hydrogen peroxide is added to a chicken liver sample exposed to lemon juice the chemical reaction will be slower and appear some bubbles within the first minute (option B).
Explanation:
The liver contains an enzyme called catalase, whose function is the degradation of hydrogen peroxide (H₂O₂), an intense reaction that produces gas and heat. <u>The activity of this enzyme must occur at an appropriate pH, so changes in pH can affect the activity of catalase</u>.
- Under normal conditions, when a liver sample is exposed to H₂O₂, bubbles and foam appear in the sample as a result of the catalase reaction.
- When the chicken liver sample is subjected to the acidic lemon juice, the reaction will occur, but more slowly.
This is because the activity of the catalase enzyme, present in the liver, continues to occur —although it decreases— and will form few bubbles over a longer period of time.
The other options are not correct because:
<em> A. At a lower pH, the reaction will not form many bubbles.
</em>
<em> C. Even if the reaction is minor, and produces very few enzymes, it will always occur.
</em>
<em> D. Although the catalase/H2O2 reaction produces heat, it is impossible for the liver to catch fire and cause evacuation from the school, even less so with a reaction whose speed has been slowed down.</em>
6 turns<span>Therefore, there is only 1 net carbon produced to play with for each turn. To create 1 surplus G3P requires 3 carbons, and therefore 3 turns of the Calvin cycle. To make one glucose molecule (which can be created from 2 G3P molecules) would require 6 turns of the Calvin cycle.</span>
Answer:
The amino acids plays an important role as they are the monomers of the protein. Proteins are present inside the cell membrane and transporters also require protein.
The hydrophobic amino acids will be present in the interior of the membrane as the cell membrane's interior is hydrophobic in nature. These helix is suitable carbonyl oxygen and amide hydrogen atoms plays important role in the peptide backbone formation and forms intrachain hydrogen bonding. The polar molecules will also get stabilize in the non polar hydrophobic environment.
both processes have the cell create double everything they already have(DNA mitochondria ect...)
in the real world your body cells replicate through mitosis
im not sure about meiosis and Q2 but i hope this helped.
