Question
The energized electron leaves photosystem _____ and is delivered to the ____ _____ _____ where its energy is used to pump ______ into the thylakoid. A high concentration of _____ in the thylokoid is used to create the molecule _____ by combining ______ and _____ by a process called ______. This happens when they force their way out of thylakoid through a protein called ATP synthase. After the electron transport chain, the electron is delivered to another photosystem (photosystem 1), where _____ energy excites it. After a photon of light energizes a pigment molecule in this photosystem, an electron is excited [energized] and passed to a primary electron acceptor, The electron acceptor passes it to _____ to reduce ______. The carbon fixation reactions occur in the ______ cycle. These reactions synthesize ______ from CO2 using the high-energy products of the light reactions: _____ and ______. This process occurs in the _______. The Calvin cycle occurs _____ times (how many)? for each G3P molecule used to produce glucose and it occurs _____ times for each glucose molecule produced. It begins with CO2 fixation, a process in which CO2 is banded to a 4-carbon sugar by an enzyme called ______. The resulting carbon compounds will use up ______ and be reduced using ______ to ultimately form glucose from _____ (how many?) G3P. Rubisco is both a carboxylase and an ________. On hot/dry days, the _______ on the leaves close, resulting in _____ CO2 and _______ O2. When this happens, rubisco blinds to oxygen, this results in a negative process called _______. Two alternative photosynthesis methods ______ and ______ use the enzyme ______ to the first bind CO2, C4 separates the processes of carbon fixation and the Calvin cycle in ______ while CAM separates them in _____. What is the purpose of photosynthesis?
Explanation / Answer
The energized electron leaves the photosystem II
10-Electron transport chain
11-H+
12- H+
13-ATP by combining ADP and Pi (inorganic phosphate)
14-ATP synthesis
15- Solar energy
16- NADP+
17-NADH
18-Calvin cycle
19-Glucose
20-ATP
21-NADPH. This process occurs in the stroma of chloroplast
22- 3 times
23- 6 times to produce 1 glucose molecule
24- PEP carboxylase
25-Malate dehydrogenase
26- NADPH
27- 2 molecules of G3P
Rubisco- is both a carboxylase and oxygenase. On hot days stomata closes on the leaves, resulting in decreased CO2 and increased O2 .when this happens, rubisco binds to O2, this results in a hegetive process called photorespiration. Two alternative photosynthesis methods CAM and C4 use enzyme PEP carboxylase to first bind CO2. C4 seperates the process of CO2 fixation and the calvin cycle in Between mesophyll and bundle-sheath cells (in space) while CAM seperates them in night and day (in time)
