Explanation:
<u>in the stroma</u>
Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Further Explanation:
Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.
Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.
Additionally,
- water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain.
- This occurs in the thykaloids, where pigment molecules like chlorophyll reside.
- Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules in the stroma. These store energy in their bonds, which can be released in respiration in the mitochondria.

Hey You!
I believe the answer should be false.
Answer:
Option A, a drug to treat high blood pressure that reversibly inhibits an enzyme catalyzing production of a chemical that causes blood vessels to contract
Explanation:
The complete question is
If you were working for a pharmaceutical company as part of a drug discovery team, which of these enzyme inhibitors would you suggest as a productive avenue for drug development?
a) a drug to treat high blood pressure that reversibly inhibits an enzyme catalyzing production of a chemical that causes blood vessels to contract
b) a drug to treat diabetes that irreversibly inhibits an enzyme in the metabolic pathway to synthesize glucose
c) a compound that acts as a competitive inhibitor for a digestive enzyme produced only in the presence of certain foods
d) a compound that inhibits enzymes by significantly changing the ph throughout the body
Solution
Productive avenue of a drug simply means producing an drug that not only treats the main disease or disorder but also functions to inhibit the causative agent activity. In case of option A, both the objectives of producing drug are met and hence it is the right choice.
High blood pressure usually affects the blood vessels by narrowing them and in severe cases may rupture them. If a drug as stated in option A is produced, it will not only rectify the effects of high blood pressure but will also prevent the blood vessels from narrowing by inhibiting the activity of enzymes responsible for producing chemical that leads to blood vessel contraction.
Hence, option A is correct
The stage in mitosis or meiosis in which duplicated chromosomes line up along the equatorial plate of the spindle.
Answer:
so it can reproduce more cells
