Why does photosynthesis require 38 ATP to make sugar but respiration only creates around 32 ATP?
Question 6 options:
Plants need more energy for building cell walls than animals do for respiration
Useful energy is lost during each chemical change
The sugar made from photosynthesis has more energy than the type of sugar used for respiration
All of the above

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
