What do your cells have to overcome the problem of needing high activation energy?
Nana76 [90]

Answer: They use enzymes.

Explanation:

Cells employ enzymes to drive and speed up their chemical reactions without being used up themselves. They are the only macromolecular biological catalysts that can start a reaction using the smallest available heat energy, thus overcoming the issue of needing high activation energy. Enzymes work by converting specific substrates to required product by binding them to their active site.

If the total amount of energy in the producer level of an ecosystem is 40,000 kilocalories, approximately how much energy is ava
Dmitry [639]

Hey there!

Answer: 400 k-cal

I remember learning that 4,000 k-cal would be approximately 40 k-cal for the primary consumers, which, that would be how much would be available. Now, if we would want for the primary consumers to consume more k-cal, it's obvious that there would then have to be more k-cal from the producers level of the ecosystem.

Formula of k-calories: k-cal÷20(4)= k-cal = k-cal × 2 = k-cal

As we plug in this formula into our problem above, our answer would be explained below.

40,000 ÷ 20 = 2,000 × 2 = 4,000 ÷ 100 = 400 k-cal

Answer: 400 k-cal
