Answer:
(d) None of the above
Explanation:
The pH of your stomach must be highly acidic, because the optimum pH for pepsin, the chief stomach enzyme, is 1.5.
(a) and (b) are wrong, because both conditions are basic.
(c) is wrong, because pH 7 is neutral.
Answer:
Cell respiration begins with Glycolysis
.
Explanation:
Glycolysis is the first and initial step in the cellular respiration. Cellular respiration is the anaerobic process, which takes place in cytosol of the cells. Two molecule of pyruvate(CH3COCOO-) are formed from 1 molecule of glucose(C6H12O6)through glycolysis. The NADH and ATP are high energy molecules formed when the free energy are released. It is the process which takes place through a series of ten enzyme catalysed reactions. 10 enzymes are required to break down the sugar molecule. It occurs in cytoplasm.
Economics - is the social science that describes the factors that determine the production, distribution and consumption of goods and services
<u>Answer:</u>
<em>Enzyme activity decrease at these temperatures.
</em>
<u>Explanation:</u>
Photosynthesis is facilitated by the action of various enzymes and involves light and dark reactions. In <em>light reactions chlorophyll absorbs sunlight and creates ATP AND NADPH</em>. In dark reactions carbon is fixed using the <em>ATP and NADPH.
</em>
The efficiency of all these activities depends on the activity of enzymes which depends on the temperature. The optimum temperature range where the enzyme activity is optimal is about <em>10°c - 20°c</em>. At low temperatures and high temperatures enzyme activity is less efficient.
<em>At a temperature above 38°c and below 0°c enzyme activity decreases.
</em>
