This type of protein speeds up chemical reactions without being consumed.

What is an enzyme?

100

This carbohydrate polymer stores energy in plants.

What is cellulose?

100

This molecule is the primary energy currency of the cell.

What is ATP?

100

After CO₂ enters a leaf through the stomata, what happens next?

What is carbon fixation?

100

In insects, air enters the body through small openings called these.

What is spiracles?

200

This cellular component modifies, sorts, and packages proteins for secretion or delivery.

What is the Golgi apparatus?

200

This process replicates the cytoplasm at the end of mitosis/meiosis.

What is cytokinesis?

200

This coenzyme carries high-energy electrons in cellular respiration.

What is NAD+?

200

After acetyl-CoA enters the Krebs cycle, what happens next?

What is formation of citrate?

200

Fish have this type of circulatory system, where blood passes through the heart once per cycle.

What is a single circulatory system?

300

This enzyme irreversibly phosphorylates glucose.

What is Hexokinase?

300

This structural polysaccharide is found in fungal cell walls.

What is chitin?

300

This molecule donates acetyl groups to the Krebs cycle.

What is CoA?

300

After a stop codon enters the ribosome’s A site, what happens next?

What is release of the polypeptide chain?

300

This process allows oxygen to move across thin respiratory surfaces without energy input.

What is diffusion?

400

This mechanism ensures enzymes are not permanently turned on by regulating activity at a site other than the active site.

What is allosteric regulation?

400

This type of bacteria carries out nitrogen fixation in aquatic environments.

What are cyanobacteria?

400

This three-letter codon signals the start of translation.

What is AUG?

400

After the release of ADH from the pituitary gland, this change occurs in the body.

What is increased water reabsorption in the kidneys?

400

This adaptation allows fish gills to maintain a concentration gradient for oxygen uptake.

What is counter-current flow?

500

This process allows eukaryotic cells to generate multiple proteins from a single gene.

What is alternative splicing?

500

This evolutionary process results in similar traits in unrelated species.

What is convergent evolution?

500

This amino acid (abbreviation) is unique among the standard 20 because its side chain bonds back to the backbone nitrogen, often breaking alpha helices.

What is pro?

500

After a protein is tagged with ubiquitin, what happens next?

What is targeting of the protein to the proteasome for degradation?

500

This group of invertebrates uses book lungs or book gills for respiration.
