Explanation

Bioenergetics is the process by which living organisms convert free energy into different forms.

Such as light energy to chemical energy in photosynthesis, or chemical energy from nutrients to kinetic energy in cellular respiration.

This conversion is essential for maintaining life and supporting various cellular activities.

Explanation

The sun is the ultimate source of energy for our planet, providing energy through solar radiation.

This energy is then converted into various forms, such as:

• Thermal energy (heat)
• Kinetic energy (wind, water currents)
• Electrical energy (generated from solar panels)
• Chemical energy (fossil fuels, biomass)
• Biological energy (food chains, ecosystems)

Explanation

In the human body, there are more than 1,000 known enzymes.

These enzymes play essential roles in catalyzing biochemical reactions.

Explanation

Changes in pH can cause enzymes to denature, losing their native structure and activity.

This is because enzymes are highly specific to their optimal pH range.

Changes in pH can disrupt the delicate balance of charges and hydrogen bonds that maintain the enzyme's active structure.

Explanation

As temperature increases, the rate of reaction initially increases due to the increased kinetic energy of the molecules.

It allowing them to overcome the activation energy barrier and react more quickly.

Explanation

The active site is a small region on the surface of an enzyme where the substrate binds, allowing the enzyme to catalyze the chemical reaction.

It is a highly specific region that is shaped to fit the substrate, allowing for efficient binding and catalysis.

Explanation

Activators are molecules that increase the activity of enzymes, often by binding to a specific site on the enzyme.

Inhibitors are molecules that decrease the activity of enzymes, often by binding to a specific site on the enzyme.

Explanation

In a constructive reaction, also known as a synthesis reaction, large molecules are formed from smaller ones.

This type of reaction involves the combination of two or more molecules to form a larger molecule, often with the release of energy.

Explanation

The presence of an enzyme does not affect the nature or properties of the end products of a chemical reaction.

Enzymes only speed up the reaction, they do not change the final result.

The end products are the same, regardless of whether an enzyme is present or not.

Explanation

Enzymes lower the activation energy, allowing the reaction to proceed faster and more efficiently.

This enables the reaction to occur with less energy input, making it more feasible and rapid.
