In the high temperature conditions, the spermatogenesis continues till the late spermatid stage, but the latter does not transform into the final sperm due to the destruction of the enzymes.doi:10.1080/00087114.1963.10796095MathurR. S.Taylor & FrancisCaryologia...
Elevated temperature during grain filling resulted in reduced single grain weight due largely to an effect of temperature on the accumulation of starch in ... SS Bhullar,CF Jenner - 《Functional Plant Biology》 被引量: 256发表: 1986年 Activities of key enzymes for starch synthesis in relation ...
The effect of high temperature on starch accumulation, starch granule populations, and expression of genes encoding key enzymes for starch biosynthesis was examined during grain development in wheat ( Triticum aestivum L. cv. Butte 86). High temperature applied from anthesis to maturity reduced the ...
Describe why you can not test the effects of two parameters (like pH and temperature) simultaneously (in the same experiment) on enzymes. Explain how measuring the effect of temperature on enzyme activity will be different from measuring the effect of enzyme concentrat...
This phenomenon may be related to the effect of enzymes. Biological enzymes are macromolecular organic matter with catalytic functions produced by organisms, most of which are proteins and a few of which are RNA [3]. Any change in temperature, acidity, or alkalinity that may inactivate the prote...
Our results showed that the effect of temperature and humidity on producing of cell wall degrading enzymes was consistent with that on disease development on tomato plants. 展开 关键词: tomato gray mold rot temperature humidity cell wall degrading enzymes ...
To improve the removal of non-cellulose impurities in enzymatic scouring of cotton,effect of temperature on the catalytic efficiency of enzymes was investigated.It was found that temperature had great effects on the catalytic efficiency of enzymes within a certain scope of treatment temperature.The tem...
What effect does changing from room temperature to 0 have on the activity of the enzyme?Enzymes:In order for chemical reactions to push forward and proceed with the formation of products, it must obtain a specific amount of energy that will fuel the reaction referred ...
Environmental warming is associated with reductions in ectotherm body sizes, suggesting that larger individuals may be more vulnerable to climate change. The mechanisms driving size-specific vulnerability to temperature are unknown but are required to fi
Effects of high temperature on activities of antioxidant enzymes Temperature stress induced production of reactive oxygen species, which can damage plant cells [42]. To protect the plants from oxidative stress and maintain normal cellular functions, plants have enzymatic scavengers including APX, CAT, ...
