Calcium
Carbon
Helium
Phosphorus
Which of the following categories of organic molecules is correctly paired with one of its functions?

Which of the following is the main reason that humans need to include carbohydrates in their diet?
Carbohydrates are broken down in cells for energy.
Carbohydrates combine to form many different proteins.
Carbohydrates act as catalysts to speed up chemical reactions.
Carbohydrates are the building blocks for cell growth and repair.
Some bacteria contain a protein called nitrogenase. Nitrogenase catalyzes, or speeds up, the chemical reaction that converts atmospheric nitrogen (N2) into ammonia (NH3). Nitrogenase is an example of which of the following?
A sugar
An enzyme
A nucleotide
An amino acid
Ovalbumin is a protein found in eggs. Which of the following best describes the molecular structure of ovalbumin?
a group of six carbon atoms joined in a ring
a chain of amino acids folded and twisted into a molecule
a set of three fatty acids attached to a molecule of glycerol
a sequence of nitrogenous bases attached to a sugar-phosphate backbone
Use the table to identify the
macromolecule being described.

DNA is an essential molecule for life. It is responsible for storing the information to make all of an organism’s proteins. Where would you find DNA in a cell?
Golgi Bodies
Nucleus
Rough ER
Vacuole
In order to maintain a plant’s structure, plants need to store water within their cells. What organelle would be responsible for storing water within plant cells?
Vacuole
Chloroplast
Mitochondria
Lysosome
Muscle cells need to quickly convert energy from food molecules into a usable form. For this reason, which of the following do muscle cells have in greater numbers than most other types of cells?
Chromosomes
Mitochondria
Smooth ER
Cytoplasm
A fish is exposed to toxins that were dumped into the pond that it lives in. Which organelle within the fish’s cells would be responsible for breaking down these toxins?
The nucleus
The Golgi bodies
The smooth ER
The lysosome
What two organelles are essential for capturing and releasing energy in plant cells?
Nucleus and Rough ER
Vacuole and Chloroplast
Mitochondria and Cell well
Chloroplast and Mitochondria
Proteins destined for extracellular release are packaged in specific vesicles. After packaging, the vesicles bud off and are stored in the cell until a signal is given for their release. When the appropriate signal is received, they move towards the membrane and fuse to release their contents.
Once proteins have been produced at the ribosomes, what two organelles work together to aid in the secretion process described above?
Golgi bodies and Rough ER
Golgi bodies and Lysosome
Mitochondria and Rough ER
Ribosomes and Smooth ER
Enzymes are proteins that have a three-dimensional shape that is specific to a particular substrate. Environmental conditions can change the shape of the protein. What is the most likely result if the shape of the enzyme changes?
The substrate will change its shape to match the enzyme.
The enzyme structure change will result in the function to not be carried out.
The products made from the enzyme and the substrate will be changed.
The enzyme will be able to bind to more diverse substrates than before.
Lysosomes are a type of organelle that contain digestive enzymes. Which of the following statements best describes where these enzymes are made?
Enzymes are a type of protein, so they are produced by ribosomes
Enzymes are a type of protein, so they are produced by the smooth ER
Enzymes are a type of lipid, so they are produced by the smooth ER
Enzyme are a type of lipid, so they are produced by ribosomes
