•
Starch is made from molecules of –
Simple Sugars
Proteins are made from molecules of –
Amino Acids
What metabolic Activity Builds Larger
Molecules from smaller ones
• Synthesis
• What metabolic activity breaks down large
molecules into smaller ones
• Digestion (Hydrolysis)
• When Carbohydrates are digested what is the
end product
• Simple Sugars (Glucose)
• What are carbohydrates used for
• Source of Energy
• When Proteins are digested what is the end
product
• Amino Acids
• What do we then do with the amino acid –
• Synthesize them into our proteins
• What important protein controls metabolism
• Enzymes
• Where did you get the amino acids to make your
enzymes
• The foods you eat
Enzymes

What is the job of Enzymes
All chemical reactions (Digestion, Synthesis etc.)
What are enzymes made of
Proteins
So what are the building blocks of enzymes
Amino Acids
Every enzymes acts upon only
One Substance
•
•
•
•
Enzymes work only in specific conditions like
Temperature
pH
Concentration
Hormones

•
What are they
Chemical Messengers
Where do the messengers go to
Cells
What on the cells do they interact with
Receptors
Why are only certain cells affected by hormones
Cells have specific receptors
Receptors
• They work according to their –
• Shape
• Play an important role in communication
between
• Cells
Feedback Mechanisms
• Maintain
• Homeostasis
•
Person is
outside and
their body
temperature
decreases

The person
begins to shiver
and blood
vessels in the
skin constrict

Body Temperature
increases
•
Carbohydrate

