34kurt

Answer:

<u>The Golgi apparatus </u>plays a central role in molecular transport after biosynthesis.

Explanation:

Transcription occurs in the nucleus during protein synthesis, followed by translation inside ribosomes. Then, new molecules join the endoplasmic reticulum to be <em><u>folded and modified</u></em>. In the Golgi, they are <em><u>tagged and separated</u></em> into lysosomes for export<em> </em><em><u>outside the cell.</u></em>

 The Golgi system comprises of several regions known as cisternae; they act as<em><u> independent microenvironments</u></em> where products requiring their own unique conditions are <em><u>converted into new, stable biomolecules</u></em>.

Why would there be a relationship between photosynthesis and temperature<br><br> Help me
Mumz [18]

Answer:

Enzyme-controlled chemical reactions combining carbon dioxide and glucose water. The photosynthetic rate is affected by the temperature much like any other enzyme-controlled reaction.

Explanation:

At low temperatures, the number of molecular collisions between enzymes and substrates limits the photosynthetic rate. Enzymes are denatured at high temperatures.

Enzymes are protein molecules used in biological reactions by living organisms. The proteins are folded in a very specific form, which enables them to effectively bind to the molecules of interest. The enzymes used for photosynthesis perform less efficiently at a low temperature between 32 and 50 degrees Fahrenheit 0, 10, and 10 degrees Celsius, which lowers the photosynthesis rate.This will lead to lower glucose synthesis and slow growth. In the case of plants in a greenhouse, this is prevented by installing a greenhouse heater and thermostat.
