Answer: Option (a) is the correct answer.

Explanation:

An atom consists of three sub-atomic particles namely protons, neutrons, and electrons.

Protons have positive charge, neutrons have no charge, and electrons are negatively charged.

Protons and neutrons reside inside the nucleus of an atom whereas electrons revolve around the nucleus of the atom. The electrons which are in the outer most shell take part in a chemical reaction and thus leads to formation of new compounds.

Hence, we can conclude that the outer electrons are the parts of an atom that are involved in chemical reactions.

During glycolysis, glucose is broken down into two molecules of pyruvate. What is the main transformation that occurs during gly
mr_godi [17]

Answer;

-Glycolysis produces pyruvate, ATP, and NADH by oxidizing glucose

Explanation;

-Glycolysis is the first of the main metabolic pathways of cellular respiration to produce energy in the form of ATP. Glucose is cleaved or broken down into two three-carbon sugars of pyruvate through a series of enzymatic reactions.

-Overall, the process of glycolysis produces a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules for the cell to use for energy. Following the conversion of glucose to pyruvate, the glycolytic pathway is linked to the Krebs Cycle, where further ATP will be produced for the cell’s energy needs.

Would areas along the shores of the Great Lakes have warmer summers and colder winters than other inland areas? Why or why not?
Klio2033 [76]

Answer:  Because the Great Lakes act as a heat source during the winter, coastal air temperatures are more moderate than the air temperature in inland areas. Winter: There is less radiation from the sun, generally making temperatures cooler. That means the lakes are warmer than the air.
