Biology
1 answer:
Sloan [31]3 years ago
4 0

Answer: 7 electrons

Explanation: In the first orbital shell it can only hold a maximum of 2 electrons.

The second orbital or energy level it can hold a minimum of 1 and maximum of 8 electrons.

Since the first shell has 2 electrons it means that the second shell has 7 electrons.

If you were to expose cells that are undergoing aerobic cellular respiration to a radioactive oxygen isotope in the form of O2,
HACTEHA [7]

Answer:

Water

Explanation:

Molecular oxygen is the terminal electron acceptor and serves to receive electrons from reduced NADH and FADH2 to reoxidize them. NADH and FADH2 are formed during glycolysis and Kreb's cycle. These reducing powers should be re-oxidized to enter in the first two steps of aerobic respiration again.

For the purpose, NADH, and FADH2 transfer their electrons to the molecular oxygen via electron transport chain. After accepting the electrons, molecular oxygen is oxidized into the water molecule. Therefore, radioactive oxygen isotope would appear in the form of a water molecule after completion of cellular respiration.

How might a plant cope with the fact that the Calvin cycle uses more ATP than NADPH, yet produces roughly the same amount of bot
nataly862011 [7]

Answer:

Photosynthesis can revert from a noncyclic to cyclic electron flow, producing more ATP than NADPH.

Explanation:

A Calvin Cycle is defined as a process by which various plants and algae takes carbon dioxide from the air and turns it into sugar, the food which the  food autotrophs needs to grow. The Calvin cycle is required for every living being on earth to survive.

Both the ATP and the NADPH are required by the Calvin cycle. It occurs in the chloroplast stroma of the plants. Calvin cycle uses more amount of ATP than the NADPH and produces roughly same amount of both the energies. Photosynthesis may revert from the noncyclic to the cyclic electron flow and it produces more ATP than NADPH.
