Enzymes only work on their specific substrates because enzyme catalysis involves enzyme and substrate binding to form an enzyme substrate complex.
In other words, the of substrate substances an enzyme can bind to leading to the specificity of enzyme activity aids in causing the correct reaction in the particular structure.
Answer:
chloroplasts
Explanation:
The process of photosynthesis takes place in organelles containing green pigment chlorophyll called chloroplasts. Chloroplasts are small organelles inside the cells of plants and algae. They absorb light to make sugar in a process called photosynthesis.
<u>Answer</u>: works optimally at 20°C
Enzymes are a broad group of biological catalysts that have the role of accelerating chemical reactions by binding to molecules and altering them in specific ways. They are essential to the correct functioning of the body.
Enzymes function only at certain temperatures and pH ranges. The enzyme shown in the graph works optimally at 20°C. This is shown by the fact that the reaction rate, enhanced by the enzyme, reaches a maximum at this temperature. The higher the temperature, the more effective the enzyme.
However, at temperatures higher than this optimal threshold, the enzyme will gradually decrease in efficiency. To high or low temperatures will have this effect.
Any forms of predatory or parasitic life may decrease, or even vanish! As then would the creatures that survived off of these organisms. I would be able to go on for a while about the different organisms of all sizes that would vanish and how they would cause other species to be affected.
Salmon are VERY important to the food chain!
Hope this helps! <span />
Length of PolyA tail is different in two cells
Explanation:
- Different lengths of Poly A tails are present for different mRNAs so when we compare two peptides translated in two different cells we have different lengths of PolyA tail
- PolyA tail is basically a long chain of nucleotides(adenine nucleotides) which are added to messenger RNA(mRNA) during processing of RNA
- It increases the stability of the molecule
- It protects the mRNA molecule from undergoing degradation in the cytoplasm
- It is involved in binding proteins which further initiates translation;introns are removed from pre mRNA before the final mRNA is exported into cytoplasm
