Answer:
it is a biochemical process that involves the oxidization of glucose to release energy with the formation of carbon dioxide and water as by products
Explanation:
Answer:
The options are
A) electrical energy.
B) mechanical motion.
C) heat and light energy.
D) electrical and heat energy.
The answer is C) heat and light energy.
Explanation:
Chemical energy in the wood is lit up by fire and a burning process begins to occur. Burning involves a substance being consumed by fire and fire aids in the conversion of some forms of energy to mainly light energy as a result of the burning flames and also to heat energy as a result of the high temperature in the form of heat which the fire brings into play.
This validates the stored chemical energy in the logs being changed into light and heat energy.
Combination of sugar molecules with other elements
Explanation:
A molecule of sugar is basically constructed of carbon, oxygen, and hydrogen atoms linked together as hydrocarbons. This hydrocarbon with C-C bonding facilitates sugar molecules to combine with other atoms and form larger molecules like amino acids, nucleotides etc.
Carbon provides four free valence electrons to share and form covalent bonds with other elements like oxygen, nitrogen, hydrogen etc. Carbon also can link and form long chains of such C-C covalent bond and forms carbon-containing organic compounds.
The carbon, oxygen, hydrogen in sugar molecules combine with nitrogen to form alkaloids and then with sulfur to form amino acids.
Amino acids are the building blocks of proteins which perform various functions as hormones, antibodies, pigments, structural proteins etc and are highly necessary for a living thing to grow and survive.
