A) Each enzyme has a narrow range of temperature and p H optima.
Which of the following contribute to the specificity of enzymes?
B) They are not altered by the enzyme-mediated reaction. One possibility for its function could be that ascorbic acid is very similar in size and shape to catechol, the substrate of the browning reaction.
If this is true, then this inhibition is most likely an example of _______ inhibition.
Explain how ATP is involved in each example you choose.
Unit 5 (Meiosis, Mendelian Genetics, DNA Replication) 17.Remember that the AP Biology exam tests you on the depth of your knowledge, not just your ability to recall facts.While we have provided brief definitions here, you will need to know these terms in even more depth for the AP Biology exam.Describe the light reactions of photosynthesis and, for both a C3 and a C4 plant, trace the path of a carbon dioxide molecule from the point at which it enters a plant to its incorporation into a glucose molecule.Include leaf anatomy and biochemical pathways in your discussion of each type of plant. Explain what occurs during the Krebs (citric acid) cycle and electron transport by describing the following: 15. For 3 of the following 5 processes involving energy transfer, explain how each functions in the cell and give an example.At that point, no amount of substrate increase will increase the rate of reaction 12. Rubisco has both carboxylase and oxygenase activities. Amylase is a digestive enzyme that breaks down starch and is secreted in the mouth of humans.Amylase functions well in the mouth but ceases to function once it hits the acidic stomach environment. Photorespiration is favored during hot, dry weather, which forces the closing of stomata and leads to increases in O2 levels within the leaf.Unit 4 (Photosynthesis and Cellular Respiration) 10.Describe the similarities and differences between the biochemical pathways of aerobic respiration and photosynthesis in eukaryotic cells.
