Answer:
The correct answer is C. A buildup of lactic acid in the tissues.
Sore muscles after vigorous exercise are the result of lactic acid accumulation in the muscles.
Vigorous exercise reduces the levels of oxygen available in the muscles due to which complete oxidation of the glucose could not take place.
Muscle cells switch to another process called as lactic acid fermentation to produce energy. In this process, lactate dehydrogenase converts pyruvate into lactate and reduces NADH to NAD⁺.
This NAD⁺ enables the continuation of glycolysis which results in the production of net 2 ATP.
In addition, influx of materials such as nutrients, WBC, anti-inflammatory compounds etc into the muscle cell (for repair) causes swelling of the muscle fibers which is also the reason for the muscle soreness.
I am pretty much sure that C. Lyases is the answer.
Let me give some information about this.
Lyases are the main groups which show peculiarity in having more than several categorised groups having more enzymes than the other four.
Hydrolase does not fit this bill instead they contain less categorised groups.
Other two groups are not even having that much groups.
Hope helps ...
1. Reduced production of waste materials
2. Increased reuse of older materials
3. Use more renewable sources of energy
4. Decrease the rate of fires through alternate means of warmth
5. Burn down less forests and find better means of farming
PP- purple homozygote
pp- white homozygote
Pp- purple hetrozygote
If these flowers cross, we obtain heterozygote offsprings with a genotype: Pp (100% of them will be like this)
Now, if those offsprings cross with each other: Pp x Pp
results:
1/4 would be purple homozygote -> PP
1/4 would be white -> pp
2/4 would be purple heterozygotes -> Pp
Genotipic ratio: 3:1 (3 are purple; 1 is white)
