Ch 8 Metabolism

What is metabolism?

• Metabolism refers to all of the chemical reactions that take place inside of organism

• Metabolism is the process by which your body converts what you eat and drink into muscle.

• Metabolism refers to the process of turning DNA into proteins

• Metabolism is the process by which your body converts energy into what you eat and drink.

What are the two main types of metabolism?

• photosynthesis and respiration

• endocytosis and exocytosis

• osmosis and diffusion

• catabolism and anabolism

What does energy coupling mean?

• the energy created by catabolic reactions is used to power anabolic reactions

• the energy created by anabolic reactions is used to power catabolic reactions

What is the role of enzymes in metabolism?

• Enzymes slow down biochemical reactions so that they happen properly

• Enzymes have no role in metabolism.

• Enzymes are only involved in the breakdown of biomolecules

• Enzymes speed up and help to regulate biochemical reactions.

What is anabolic metabolism?

• Anabolic metabolism is the set of metabolic pathways that break down smaller molecules into larger ones, releasing energy.

• Anabolic metabolism is the process of converting energy into ATP.

• Anabolic metabolism is the breakdown of larger molecules into smaller ones, releasing energy.

• Anabolic metabolism is the set of metabolic pathways that build larger molecules from smaller ones, requiring energy input.

What is a metabolic pathway?

• A type of biochemical reaction that leads to larger and larger biomolecules

• A type of biochemical reaction that leads to smaller and smaller biomolecules

• The pathway that cells take to move from one type of tissue to another

• A series of linked biochemical reactions where the products of one reaction become the reactants of the next

What is the ATP molecule and its role in energy metabolism?

• ATP is a molecule that stores and releases energy in cells.

• ATP is a molecule that is only found in plants.

• ATP is a molecule that is used for cell division.

• ATP is a molecule that is produced in the mitochondria.

What factors can affect metabolic rate?

• Height, weight, and blood type.

• Eye color, hair color, and shoe size.

• Favorite color, favorite food, and favorite movie.

• Age, body composition, physical activity level, and hormone levels.

Which biochemical process is associated with catabolism?

• hydrolysis

• dehydration synthesis

Which biochemical process is associated with anabolism?

• hydrolysis

• dehydration synthesis
