Biomolecules
This biomolecule is the body's main source of quick energy and is found in bread, pasta, and fruit.
What are carbohydrates?
These biological molecules speed up chemical reactions in living organisms.
What are enzymes?
This is the process by which a cell grows, copies its DNA, and divides.
What is the cell cycle?
This molecule contains the genetic instructions for living organisms.
What is DNA?
This type of cell does not contain a nucleus.
What is prokaryotic cell?
This biomolecule stores long-term energy and includes fats, oils, and waxes.
What are lipids?
This is what attaches to the enzyme.
What is the substrate?
During this stage of the cell cycle, the cell grows and performs its normal functions.
A nucleotide is a monomer of DNA that is made of what 3 things?
What is a phosphate, a sugar, and a nitrogen base
Which of the two types of cells is larger, prokaryotic or eukaryotic?
What is eukaryotic?
These biomolecules help build and repair tissues and are made of amino acids.
What are proteins?
This is the molecule that leaves the enzyme after being activated.
What is the product?
During this stage of interphase, the cell copies its DNA.
What is S phase?
These are the four nitrogen bases found in DNA.
What is adenine, thymene, guanine, cytosine, or ATGC?
This structure surrounds the DNA in eukaryotic cells and protects the genetic material.
What is the nucleus?
DNA and RNA belong to this group of biomolecules, which store and transmit genetic information.
What are nucleic acids?
When an enzyme loses its shape because of extreme temperatures or pH, this process occurs.
What is denature?
These are the four stages of mitosis, in the correct order.
What is prophase, metaphase, anaphase, telophase?
If one DNA strand has the sequence A-T-C-G, this is the complementary DNA sequence.
What is T-A-G-C?
Plant, animal, fungi, and protist cells all belong to this category.
What are eukaryotic cells?
A student eats chicken and eggs to help build muscle. Which biomolecule is most important for building and repairing muscle tissue?
What are proteins?
An enzyme works best at 37°C. What might happen to its activity if the temperature becomes extremely high?
Its shape may change, causing it to lose its function.
A cell has completed mitosis, but the cytoplasm has not divided. What process must happen next to produce two separate daughter cells?
What is cytokinesis?
A DNA sequence originally reads A-T-C-G. After a mutation, it reads A-T-G-G. What type of mutation occurred?
What is a substitution mutation?
A scientist observes a cell with DNA, ribosomes, and a cell membrane, but no nucleus or other membrane-bound organelles. What type of cell is it?
What is a prokaryote?
