What happens when chemical bonds break and new bonds form?A.) Physical change
B.) A chemical reaction
C.) Matter is surface area increases
D.) Destroyed

Answers

Answer 1

Answer:

When chemical bonds break and new bonds form then the Chemical Reaction takes place. The option B is the correct option.

A chemical reaction is the transformation of one or more chemicals, known as reactants, into one or more new substances, known as products. Breaking and establishing chemical bonds are the processes that change reactants into products.

Chemical reactions are an essential component of technology, society, and life itself. Many tasks that involve chemical reactions include burning fuels, smelting iron, creating glass and pottery, brewing beer, and making wine and cheese.

Thus, the correct option is B. A Chemical reaction.

. A person rides his bicycle several miles. What process is used by the cells in his legs to release energy at the beginning of the ride and at the end what cause the pain in his legs

Answers

Answer:

At the beginning, aerobic respiration is used by his legs to generate energy when there was still sufficient oxygen intake for energy to be generated via oxidative phosphorylation.

Towards the end of the ride, his legs are generating energy through anaerobic respiration due to insufficient oxygen intake to keep up with the energy requirement of his muscles as he cycles continuously. Through anaerobic respiration, pyruvate from glycolysis is converted to lactate by lactate dehydrogenase instead of being channelled to the mitochondria for oxidative phosphorylation. The accumulation of lactate in his muscles is what causes the pain in his leg. After he stops the activity, the pain would reduce as lactate is transported to the liver to be reconverted back into pyruvate.
