Which chemical formula represents a carbohydrate?
The major role of carbohydrates in the human diet is to
form the membranes that surround mitochondria
act as a catalyst for cellular reactions
supply energy for the body
provide building blocks for amino acids
Base your answer to the question on the diagram and on your knowledge of biology. The diagram represents a portion of a starch molecule. The building blocks for this starch molecule are
Eating a sweet potato gives energy for human life processes. What is the source of energy in this sweet potato?
protein molecules stored within the potato
water molecules absorbed by the potato plant
starch molecules made by photosynthesis
vitamins and minerals found in the soil
Which compound has the structural formula shown in the diagram?
There are over 2000 kinds of edible insects in the world, and they are becoming an increasingly popular source of protein. One cup of cricket flour contains over 28 grams of protein. The building blocks of the protein in cricket flour are
Proteins, starch, and DNA are similar in that they are all
parts of genes
made of amino acids
made of simple sugars
The shape of a protein molecule directly determines its
movements through the cytoplasm
functions inside and outside of cells
roles in building water molecules
circulation throughout the body
Three days after an organism eats some meat, many of the organic molecules originally contained in the meat would be found in newly formed molecules of
In plants, simple sugars are least likely to be
linked together to form proteins
broken down into carbon dioxide and water
used as a source of energy
stored in the form of starch molecules
Which substances are inorganic compounds?
water and salts
proteins and carbohydrates
fats and oils
enzymes and hormones

The characteristic that all lipids have in common is
made of lots of double bonds
low energy content
acidic when mixed with water
do not dissolve in water
Which of the following is NOT a function of lipids?
long term energy
building of muscles

Which food listed below would be composed of mainly protein?
Which of the following best describes a DNA molecule?
made of amino acids
Why is DNA important?
it is very small and very complicated
it's in everything
it serves as the blueprint for traits of all living things
because we eat it every day for energy
