Photosynthesis is defined as the chemical process, wherein carbon dioxide in the presence of water and radiant energy gets converted to glucose (chemical energy), giving out oxygen as byproducts. In the equation, the combining reactants and resulting products are expressed along with their respective numbers of molecules. Putting this in a simplified formula, the following equation represents this process.
CO2 + H2O + Light energy → C6H12O6 + O2
Considering this equation, how plant lovers (plantitos and plantitas) able to cultivate their plants?
Thylakoids were isolated from chloroplasts and incubated in the dark in an acidic solution (pH 4) to equilibrate the pH. After 30 minutes, the thylakoids were transferred to a basic solution (pH 8) and kept in the dark. Will this system produce ATP? Explain. Will this system produce G3P? Explain.

- Photosynthesis and aerobic cellular respiration both rely on electron transport chains to generate ATP. Which of the following does not correctly identify similarities and differences in the ETCs of these processes? a) Electrons delivered to the ETC are used to generate a proton gradient across the membrane b) In photosynthesis, the facilitated diffusion of protons across the membrane generates ATP and glucose molecules; in cellular respiration, this process generates ATP c) In photosynthesis, electrons are delivered to the ETC by NADPH; in cellular respiration, electrons are delivered to the ETC by NADH and FADH2 d) In prokaryotes, active transport moves protons across the cell’s plasma membrane during photosynthesis and cellular respirationarrow_forwardIn photosynthesis, CO2 carbon atoms are transformed to glucose carbon atoms. (a) Are the CO2 carbon atoms being oxidized or reduced in this process? (b) Do the CO2 carbon atoms move to a higher or lower energy state in this process?arrow_forwardThe equation for photosynthesis is 6CO2 + 6H2O + Sunlight --> C6H12O6 + 6O2.

- The products of photosynthesis are carbohydrate molecules and O2. From which of the substrate molecules (CO2 or H2O) are the oxygen atoms derived?arrow_forwardThe process of photosynthesis can be modeled in various ways. For example, a chemical equation is one way to represent photosynthesis. 6CO, + 6H,0 ++ +→ 60, + C,H,,O,arrow_forwardIn biochemistry, the exergonic process ofconverting glucose and oxygen to carbon dioxide and water in aerobic metabolism can be considered the reverse of photosynthesis,in which carbon dioxide and water are converted to glucose andoxygen. Do you expect both processes to be exergonic, both endergonic, or one exergonic and one endergonic? Why? Would youexpect both processes to take place in the same way? Why?arrow_forward
- Plants undergo both photosynthesis and cellular respiration. Why don’t plants simply use the ATP pro¬duced in the light reactions of photosynthesis to drive cellular processes? A) The ATP produced during photosynthesis is chemically different from the ATP produced during cellular respiration and cannot be used for anabolic reactions B) ATP cannot be stockpiled so the plants would have no energy during non-daylight hours C) The plants have no way of getting the ATP made during photosynthesis out of the chloroplasts to the rest of the cell D) Plants rely on cellular respiration to remove excess O2 and prevent photorespirationarrow_forwardFor the following questions, choose one to discuss: chloroplast/photosynthesis State at the outset which one you will discuss. A) What role do proton gradients play in the process of photosynthesis proton gradients allow B) Where are proton gradients formed? Within what structures are they seen in chloroplasts How do the structures help them to maintain a gradient? C) Explain where and how the chloroplast or mitochondria uses passive transport and active transport to complete photosynthesis or cellular respiration.arrow_forwardBlue-green algae (cyanobacteria) form heterocysts when deprived of ammonia and nitrate.
