<span>If the PH and temperature changed significantly beyond the enzyme optimum level it will become denatured and then the enzyme would not work.
The Enzyme is a biological catalyst which speeds up a reaction. The Enzyme has molecules which act upon as substrates and then it converts those substrates into different molecules which are called products.
The study of the enzyme is known as enzymology, and they are well known to catalyze more than 5,000 biochemical reaction types.</span>
Answer:
In explanation.
Explanation:
Relationship between photosynthesis and cellular respiration.
-Both involve in the production of energy
-Both involve the exchange of gases
-Both the process takes place in cell organelle which was considered as endosymbiotic organism. They are chloroplast and Mitochondria, Photosynthesis takes place in the Chloroplast whereas respiration takes place in mitochondria.
-At critical condition both have an alternate pathway.
Extra: differences between photosynthesis and cellular respiration.
-Photosynthesis takes place in the chloroplast, whereas respiration takes place in mitochondria.
-Photosynthesis involves the production of carbohydrate and respiration involve breaking of carbohydrate.
-Photosynthesis occurs only during the presence of sunlight whereas respiration occurs all the time.
-In the photosynthesis process Oxygen is released whereas in respiration Oxygen is utilized.
<span>Damming a river has a variety of effects on the freshwater ecosystem, more than just altering the flow from A to B. Dams create calm bodies of water, changing overall temperature regimes and sediment transport, leading to conditions which tend to favour generalist species. Loss of specialist species, particularly endemics, changes the community structure and leads to biotic homogenization. A dam will withhold sediment in the reservoir, not just decreasing the amount of substrate available to local freshwater species, but even impacting diadromous, estuarine and marine species much further downstream. The competition between resident species for food and breeding sites will increase as damming isolates populations, and perhaps more importantly, damming completely restricts migratory fish species. Isolation may lead to decreases in genetic diversity and therefore puts species at greater risk from disease. All of these effects may be exacerbated by changes in the surrounding land use. Overall, damming river flow will lead to both a loss of native species, but also an increase in exotic species which are more likely to become established in degraded habitats. For this reason, dams are one of the greatest global threats to freshwater biodiversity.</span>
