Explain how each of the following factors affect the rate of photosynthesis 1) temperature 2) inorganic ions
Illusion [34]
The main variables which affect photosynthesis are light, water, CO2 concentration and temperature.
On a deeper level, other factors like amount of chlorophyll, availability of nutrients (eg Mg is needed for chlorophyll synthesis) will also affect the rate of photosynthesis, though these are rarely covered in discussion of this topic.
The thing is that photosynthesis will be held back by whichever factor is in shortest supply.
As I sit in my study in England, the sun is shining brightly, but the temperature outside is only 5ºC. I suspect the rate of photosynthesis is limited by temperature today.
Yesterday was a dull day, but in the middle of the day it was not cold and I suspect there wasn't enough light for photosynthesis. If I had turned the security lights on my house on, the plants in my garden might (possibly) have photosynthesised faster.
In summer, some farmers growing crops in glasshouses actually increase the amount of carbon dioxide in the air as all their plants have plenty of water and light and the temperature is near the best possible for photosynthesis.
A good way to investigate this might be with the help of algae and you can use the 'Immobilised Algae' practical for this.
Although water is needed as a raw material for photosynthesis, don't bother trying to investigate water as a variable - plants normally wilt and wither long before water restricts photosynthesis at the biochemical level. They need water to support the plant to face the sun as well as a raw material of photosynthesis.
The simplest equation for photosynthesis:-
Carbon dioxide + water -----(in light, with chlorophyll and enzymes)----> sugar + oxygen
Temperature speeds up all chemical reactions - photosynthesis is no exception.
Enzymes work better in warm conditions (up to about 50ºC when enzymes start to be destroyed by heat).
The idea to get across is that different conditions will be most important on different occasions. This morning, my garden could do with more warmth - yesterday, it could do with more light / sun!

CLINIC NOTE
Bingel [31]

Answer:

99396

Explanation:

CPT Code 99396:

It is a periodic and easy-to-understand precautionary medicine system that are basically well-patient examinations for conventional patients proffering for reevaluations and/or management of the entire health form and fitness with code selection reliant on the patient's age.

These services entails relevant patient history and examination, guidance/recommendation that involves personal predisposing factors, and any laboratory and/or medical diagnosis or procedures that was determined. Clinicians are not expected to outline minimal or self-limiting circumstances or complaints that was stated during the period of the preventive examination when those complications do not need any extra work or demand of carrying out the key constituents of a problem oriented E/M service.

Hope this helps!
