Answer:
There are two-phase of glycolysis preparatory phase and payoff phase. In the preparatory phase, ATP is used therefore it is called the energy investment phase and in the payoff phase, ATP is produced so it is called the energy generation phase.
In preparatory phase 2 ATP is used and it is converted into ADP and in pay off phase 4 ATP is produced from ADP. Therefore by subtracting 2 from 4, we get 2 ATP. Therefore in glycolysis, energy investing and energy harvesting step results into two ATP molecules.
The main difference between temperate forests and tropical rainforests is their location. The location in turn contributes to climate, type of foliage and the way it looks. <span>Temperate forests are in both the northern and southern hemispheres between the tropics and the polar regions. Temperate rainforests are usually close to continental coasts.</span>
Advantages of sky: produce rain ( that is needed for plants, crops, drinking, animals, etc) , Holds the clouds, Sun, moon, we can view the beautiful design of nature by studying the sky, and clouds .
disadvantages: produces potentially harmful weather catastrophes like hurricanes, lightning, thunder, hail, tornados that destroys the original design and performance of nature, killing people and destroying homes, when the sky doesn't produce rain famine occurs.
The living cell main source of energy is the sun.
