  carbohydrates

12
Who am I?
13
Answer

• Fatty acid building block of FATS/TRIGLYCERIDES.
  This one is a SATURATED fatty acid

14
Who am I?
15
Answer

18
Who Am I?
19
Answer

• polymer

20
Which of the following DOESNT belong?

• Glucose
• Lactose
• Galactose
• Fructase

21
Answer

• Fructase the rest are sugars (all end in ose)
  ending in ase means its an ENZYME

22
Who am I?
23
Answer

• Protein a chain of amino acids

24
Which element is present in maltase but not
maltose?

• Carbon
• Hydrogen
• Oxygen
• Nitrogen
• Calcium

25
Answer

• Maltase is an enzyme, which is a protein. Maltose
  is a sugar, or a carb. So, proteins have CHONS,
  while carbs contain CHO. Sothat means that the
  answer is NITROGEN.
