Metabolism
Metabolism is the sum of all the reactions in a cell or the body.
Key facts about metabolism
Metabolism is the sum of all the chemical reactions that occur within a living organism. It includes processes that break down molecules to release energy (catabolism) and those that build up molecules, requiring energy (anabolism). These reactions are essential for maintaining life, providing energy, and supporting growth and repair.
Metabolic Conversions In Plant Cells
Glucose to Cellulose
Glucose to Starch
Glucose to Amino Acids
Metabolic Conversions In Animals and explain
Glucose to Glycogen: glucose is stored as glycogen, a form which allows for energy storage and release when needed
Lipid and Protein Metabolism
Lipid Synthesis & Protein Metabolism
Explain Protein Metabolism
Protein Breakdown: Humans require a small amount of dietary protein. Excess proteins are broken down into chemical urea, which is excreted by the kidneys.
Explain lipid synthesis
Lipid synthesis: One glycerol molecule reacts with three fatty acids to form a lipid molecule, which is crucial for cell membrane structure.
Explain glucose + nitrate ions = amino acid usage
the use of glucose and nitrate ions to form amino acids which in turn are used to synthesise proteins
What is the energy transferred by for metabolism so it can be used by organism for?
The energy transferred by respiration in cells is used by the organism for the continual enzyme controlled processes of metabolism that synthesise new molecules.
