Answer:

Reactions require an input of energy to initiate the reaction; this is called the activation energy (EA).

Activation energy is the amount of energy required to reach the transition state.

The source of the activation energy needed to push reactions forward is typically heat energy from the surroundings.

For cellular reactions to occur fast enough over short time scales, their activation energies are lowered by molecules called catalysts.

Enzymes are catalysts

Why does the cell go through elaborate process to convert glucose into carbon dioxide and water?

Tems11 [23]

Cellular Respiration. Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water. The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell.

Answer:

C. could not provide a mechanism for moving continents

Explanation:

Without the discovery of magnetic reversals recorded on the ocean floor, scientists could not provide a mechanism for moving continents.

Magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.

Asymmetric movement of tectonic plates leads to movement of continents and the degree of asymmetry varies with the same rythm of the magnetic reversal rate.

Hence, discovery of magnetic reversals are important to identify the mechanism for moving continents.

There are six classes of nutrients that must be considered when planning your diet: water, proteins, carbohydrates, fats, vitami

KiRa [710]

Answer:

Essential nutrients cannot be synthesized by the human body but are required for optimal functioning. Therefore. They must be obtained from food. Omega-3 fatty acids are prime examples.

You consume macronutrients (water. proteins, carbohydrates, and fats) in large quantities as opposed to micronutrients which you consume in small quantities

Dehydration can develop very quickly when exercising in hot/humid weather conditions.

Proteins are also called 'bodybuilders" due to their function within the body. Amino acids are the building blocks of proteins.

Explanation:

Essential nutrients are those nutrients that are required for the proper functioning of the body but cannot be synthesized by the body. They are obtained from external sources such as vegetables or synthesized artificially in the laboratories. Micronutrients as the name implies are taken in small amounts. Examples are the different types of vitamins.

Dehydration occurs when a person loses a good amount of water through sweating or urination. It can easily occur while exercising in hot weather conditions. Proteins repair the cells in our body and are, therefore, rightfully referred to as bodybuilders. Amino acids form proteins.
