XXXXXXXXXXXX and Questions
[1] How XX XXXXXXXXXXX involved during XXXXXXXXXXXXXX?
XXXXXXXXXXX XX a green photosynthetic matter in plants, algae. Its main role is XX absorb light from XXX sun. XXXXX XXXXXX absorbed is used XXX combining XXXXX and XXXXXX dioxide XXXX sugars XXXXXX XXXXXXXXXXXXXX (Mishra, 2017). XXXXXXX light XXXXXX photosynthesis XXX XXX XX XXXXXXXX in plants thus it is XXXXXXXXX to XXXX XXXXXXXXXXX XX help XXX XXXXX absorb light energy XXXX XXX XXX.
[X] XXXX are enzymes? XXXX XXXX do XXXX XXXX in biological and chemical reactions?
Enzymes are XXXXXXXXX XXXXXX XXXX XXX XXXXXXXX XX the rate XX chemical reactions in XXXXXX XXX animals. XXXXX main role is XX XXX XX XXXXXXXXX on the molecules XX XXXXX a XXXXXX in a plants and XXXXXXX. XXX changes XXXXXX on XXX XXXXXXXXX lead to creation of a XXX XXXXXXX. XX the XXXXXXXXX in which they speed XX, they XXXXX XXX XXXX XX just like XXX other catalysts XXXXX XXXX XXXX is XX speed XX XXXXXXXXX.
[X] XXX might XXXXXXXXXXX in XXXXXX XXXXXXXXXXXXXX XXXXXX XXXXX XX XXXXXXXXXXXXXX XXX respiration?
XXXXXXX in XXXXXXXXXXXXXX XXX respiration XXX XXX directly related. XXXXXXX, they affect the molecules involved in XXX XXX processes. During XXXXXXXXXXX, XX XXXXXXX are XXXXXXXXX, by XXXX low or high temperatures, the XXXXXXX slows XXXX. When XXXXXXX have XXX XXXXX environment (best temperature, XXXX XXXXX up XXX XXXXXXX (Lambers &XXX; XXXXXXX, 2019). XXXXXX photosynthesis, XXXX temperature XX XXXXXXXXX the enzymes XXXXXXX XXXXXXX more XXXX increasing XXX rate of XXXXXXXXXXXXXX. However, when XXX temperature becomes too XXXX, enzymes XXX denatured XXXX XXXXXXX a decrease in XXX rate of XXXXXXXXXXXXXX.
[X] Show XXXX oxygen XXXXXX XXXX XXXXXXXXXXX XXX the Sun-XXXXXXX data XXX.

[X] XXXXX your XXXXXXX XXX change in oxygen concentration XX a reference, XXXXXXX whether your results from Procedure I XXXXXXX XXXXXXXX findings about differences in XXX amount of XXXXXXXXXXX XXXXXXXXXX XXX XXX-adapted XXX XXXXX-XXXXXXX XXXXXX.
The results for XXXXXX in oxygen XXXXXXXXXXXXX in XXX sun-adapted leaf XXX 0.XXXXXXXX/s XXXXX that in XXX XXXXX-adapted XXXX XX X.252ppm/s. XXX differences in XXX rates of XXXXXX XXXXXXXXXXXXX show XXXX XXXXXXXXXXX XXXXXXXXXXXXX is XXXXXXXXX in XXX XXX XXXXXX. XXXX, XXX XXXXXXX confirm that XXXXXX XXXXXXXX XXXXXX photosynthesis XX XXXXXXXXXXXX XX XXX amount of chlorophyll in XXXXXX. Due XX XXX high production of light in XXX sun-XXXXXXX XXXXXX, they XXXX XXXX chlorophyll compared to the XXXXX-XXXXXXX leaves.
[X] What XX the XXXXXXXXXX between photosynthesis rate and net photosynthesis XXXX? Which XXXX are you determining in this XXXXXXXXX? Explain.
XXXXXXXXXXXXXX rate XX the XXXX XX which a XXXXX XXXXX in XXXXX XXXXXX to fix it in carbon XXXXXXXXX XXXXX XXX XXX XXXXXXXXXXXXXX XXXX XXXXX the rate XX XXXXX XXXXXX fix XXXXXX XXXXXX photosynthesis.
[X] XXXXXXX why (or XXX not) you would expect respiration to XXXXX when XXX XXXXXXXXXXXX XX XXX%?
I XXXXX expect respiration to occur when XXXXXXXXXXXX is 100% because light has XX direct effect the XXXX XX respiration. XXXXXXXXXX XXXXX XXXXX however increase temperature which XXXX XXXXXXXX enzymes XXXXXXXXX thus increasing the rate of XXXXXXXXXXX.

[10] XXXXXX Calculation: Show your oxygen change rate calculation XXX XXX XXX-XXXXXXX data XXX.
Oxygen change XXX the XXX adapted XXXX XXX is -10.80 while the time elapsed are 40 seconds. Therefore, XXX XXXXXX rate for the XXX-XXXXXXX leaves XX -XX.XX/XX= -X.27ppm/s
[XX] Sample XXXXXXXXXXX: Show your XXXXXX XXXXXXX XXXXXX XXXX XXXXXXXXXXX XXX the Shade-Adapted XXXX run.

[XX] XXXX XXXXX XX the XXXXXXXXXXXXXX rate if you XXXXXXXX it XX 0% XXXXXXXXXXXX in XXXXXXXXX II? Explain your XXXXXX. Cite your results XXXX Procedure I XX XXXXXX XXXX XXXX explanation.
XXX XXXX XX XXXXXXXXXXXXXX depends mainly on XXXXXXXX, temperature and XXX. XX XXX of the XXXXX factors XX XXXXXX, XXX XXXX of photosynthesis XXXXXXXXX. XXXX the procedure X XXXXXXX XXXXXXXX, the XXXX of XXXXXXXXXXXXXX is quite XXXX XXXXXXX XX XXXXXXXX of XXXXX. XXXXXXX, if XXXXXXXXXXXX XX XXXX as in the XXXXXX XXXXXXXXX, XXX XXXX XXXXX be XXXXX XX zero. XXXXX XX an important XXXXXX in XXXXXXXXXXXXXX thus without it XXX XXXXXXX reduces (XXXXXXX, XXXX). XXX XXXXXXXXXXXX in procedure X is 100 % XXXXX XXX XXXX of XXXXXXXXXXXXXX is XXXXXX XXXX in procedure XX where XXXXX XX 0% illumination.

XX] Sample Calculation: Show your oxygen XXXXXX rate XXXXXXXXXXX XXX the XXX-Adapted data run.
The XXXXXX XXXXXX rate for the XXX-adapted run XX 3.62 while XXX XXXX XXX the same is XX XXXXXXX. XXXXXXXXX, XXX XXXXXX XXXXXX rate is X.XX/40
[XX] Based on the data you XXXXXXXXX in XXXXXXXXXX I (XXX% illumination) and XXX (XX% illumination), which XXXXXX XX leaves XXXXXXXX the XXXX XXXXXX: XXX-XXXXXXX or XXXXX-XXXXXXX? Explain how XXXX XXXXXXX XXXXXXX your XXXXXX.
XXX photosynthesis XXXX in XXXXXXXXX I XXXXX light XXXXXXXXXXXX is 100% XX higher than in XXXXXXXXX XXX XXXX XXX illumination is 15 %. XXXXXXXXX, oxygen produced in XXXXXXXXX I for XXX sun-XXXXXXX leave is more than the one XXXXXXXX for XXXX XXXXXX in XXXXXXXXX III XXX XXX XXXXX-adapted XXXXX in procedure I. Oxygen produced at 100 % is higher in XXX XXX-adapted XXXX (X.XXXXX) and XXX in XXX XXXXX-XXXXXXX leaf (0.252). In procedure III XXXXXXX XXXXXX is produced in the XXXXX-adapted XXXX (X.XXXXX). The XXX-XXXXXXX leaf has XXXX XXXXX energy than XXX other leaves hence XXXXXXXX more XXXXXX because of the high rate of XXXXXXXXXXXXXX.
[XX] XXX XXXX XXXXXXX XXXX XXXXXXXXX II XXX XXXXXXXXX XXX XXXXXXXXXX XXXX research findings that there XXX XXXXXXXXXXX in XXXXXXXXXXX production and enzyme activity XXXXXXX XXXXX-adapted XXXXXX XXX sun-XXXXXXX leaves? XXXXXXX your reasoning. Cite your results XXXX XXXXXXXXX XX XXX Procedure III XX support your XXXXXXXXXXX.
Procedure II has X% XXXXXXXXXXXX while XXXXXXXXX III has XX % illumination. From the XXX XXXXXXXXXX, XXX oxygen XXX carbon dioxide XXXXXXXX XXX XXXXXXXXX. Oxygen XXXXXXXX XXX the shade-adapted leaf in procedure XX is -X.XX XXXXX that XXX the XXX-XXXXXXX XXXX XX -X.XX. In procedure XXX, the oxygen XXXXXXXX in XXX shade-XXXXXXX XXXX XX 0.15675 while that XXXXXXXX in the XXXXX-adapted leaf XX 0.0905. XXXXXXXXX XXXXX XXX leaves in XXXXXXXXX XXX XXXXXXXXX XXX XXXX XX enzyme activity and XXX XXXXX XXX XXXXXXXXXXX XXXX the XXXXXX produced in both XX positive. In XXXXXXXXX XX, the illumination is XX 0% XXXXXXX that XXXXX is XX light for XXX XXXXXX. Decreased XXXXX reduces XXX rate XX enzyme reaction XXXX reducing XXX rate of XXXXXXXXXXXXXX to give XXXXXXXX XXXXXX. For chlorophyll, XXXXX is XX light energy to XXXXXX thus there is a negative value XXX photosynthesis.
