How are the functions of a carbohydrate and lipid similar?

Both are replicated during meiosis.

Both lower the activation energy of reactions.

Both dissolve nutrients in the digestive system.

Why are proteins among the most diverse molecules?

Amino acids can link up in different combinations.

Amino acids are made up of more than 20 different proteins

How are lipids and enzymes different?

lipids store energy and enzymes act as catalysts to speed up reactions

lipids build structure and enzymes transport (carry) substances through the body

lipids support other structures and enzymes change the pH of a substance

lipids control functions and enzymes denature substances

What is the function of hemoglobin?

What is the function of insulin?

regulates (controls) the glucose (sugar) in the blood

transports oxygen in red blood cells

acts as a catalyst (speeds up) for chemical reactions

What is the function of enzymes?

acts as a catalyst (speeds up) for chemical reactions

transports oxygen in red blood cells

regulates (controls) the glucose (sugar) in the blood

What is the function of glucose?

polysaccharide/complex carbohydrate; stored glucose in animals (in liver and muscles) - ready for later use

monosaccharide/simple sugar; main source of energy in the body

polysaccharide/complex carbohydrate; in plant cell walls - gives structure and support and is also called fiber

polysaccharide/complex carbohydrate; stored glucose in plants; gives long-lasting energy

What fact about enzymes does this series of pictures convey (point out)?

enzymes are specific and will act on only on substrates that fit in it

enzymes can change shape to act on any substrate it needs to

there are only 3 different shapes of enzymes

heating enzymes changes its shape

Which characteristic is used to determine one amino acid from another?

whether there is N present or not

Plant, animal, fungi, and protists all belong to which grup of cells? Why?

eukaryotes because they have a nucleus and organelles

prokaryotes because they have no nucleus or organelles

prokaryotes because they have a nucleus and organelles

eukaryotes because they have no nucleus or organelles

What is the function of the mitochondria?

produces energy for the cell from the food

controls what goes in and comes out of the cell

What is the function of the chloroplast?

produces energy for the cell from the food

controls what goes in and comes out of the cell
