The answer to this question is :
D. Obstacle Evaluation
Answer:
By preventing the synthesis of DNA halting cell growth.
Explanation:
Fluorouracil and methotraxate prevent the synthesis of the neucleoside Thymidine thus preventing DNA replication and elongation. Methotraxate has a structure analogous to Folic acid which is important for thymidine synthesis. Thus, it acts as a competitive inhibitor on dihdrofolate reductase an enzyme that is essential for tetrahydrofolate formation, a folic acid derivative.
Fluorouracil acts by inhibiting thymidylate synthase which catalyses an essential step in Thymidine synthesis.
Answer:
A photosynthetic cell within a plant leaf produces chemical energy, stored within glucose molecules.
Explanation:
The energy captured from sunlight by Photosystems in chlorophyll is used to split a water molecule and reduce carbon dioxide to carbohydrates. This energy from sunlight is therefore stored in the chemical bonds of the glucose molecules. It is thereafter harnessed during cellular respiration when the chemical bonds of glucose are broken and the energy transferred to make ATP molecules.
