This biomolecule, such as glucose or starch, is the cell's primary source of quick energy.

What are carbohydrates

100

The biological process of maintaining a stable, balanced internal environment inside a cell or organism.

What is homeostasis?

100

Often called the "powerhouse" of the cell, this organelle generates usable ATP energy through cellular respiration.

What is the mitochondria?

100

The main energy-carrying molecule created during cellular respiration that fuels cellular work.

What is ATP? (adenosine tri phosphate)

100

Enzymes belong to this major class of biomolecules.

What are proteins?

100

Uncontrolled cell division caused by disruptions in cell cycle regulation leads to this disease.

What is cancer?

200

These hydrophobic biomolecules, including fats and oils, provide long-term energy storage and make up the cell membrane.

What are lipids?

200

The movement of solute molecules across a membrane from high to low concentration without using cellular energy.

What is passive transport (or diffusion)?

200

Tiny organelles present in both prokaryotic and eukaryotic cells that assemble proteins.

What are ribosomes?

200

 The gas reactant required for aerobic cellular respiration, which is released as a product during photosynthesis.

What is oxygen?

200

 Enzymes act as biological catalysts, meaning they speed up chemical reactions by lowering this specific energy barrier.

What is activation energy?

200

During the S phase of interphase, the cell doubles its genetic material through this critical molecular process.

What is DNA replication?

300

Made of monomers called amino acids, these biomolecules build cell structures and power cellular machinery.

What are proteins?

300

The specific term for the passive diffusion of water molecules across a selectively permeable membrane.

What is osmosis?

300

This organelle modifies, sorts, and packages proteins and lipids into vesicles for intracellular transport or secretion.

What is the Golgi apparatus (body)?

300

This gas is taken in by photosynthetic organisms and released as waste during cellular respiration.

What is carbon dioxide? (CO2)

300

The specific reactant molecule that binds to an enzyme during a chemical reaction.

What is a substrate?

300
  • The long stage of the cell cycle where a cell grows, carries out normal metabolic functions, and duplicates its DNA.

What is interphase?

400

DNA and RNA belong to this biomolecule group, which stores and transmits genetic information.

What are nucleic acids?

400

 Cellular transport that requires energy (ATP) to move substances against their concentration gradient (low to high).

What is active transport?

400

Unlike eukaryotic cells, these simpler single-celled organisms lack a membrane-bound nucleus.

What are prokaryotic cells

400

Based on conservation of matter, these two chemical molecules are the inputs/reactants of cellular respiration and the outputs/products of photosynthesis.

What are glucose (C6H12O6) and oxygen (O2)?

400

The specific region on an enzyme where the substrate binds and the chemical reaction takes place.

What is the active site?

400

The final step of cell division where the cell's cytoplasm splits to form two separate daughter cells.

What is cytokinesis?

500

This specific monomer consists of a phosphate group, a 5-carbon sugar, and a nitrogenous base

What are nucleotides?

500

A form of active transport where a cell engulfs large particles or fluids by folding its membrane inward.

What is endocytosis?

500

 Plant cells feature a large central version of this membrane-bound organelle used primarily for water storage.

What is a vacuole?

500

The anaerobic process cells use to produce small amounts of ATP when oxygen is unavailable.

What is fermentation?

500

Extreme heat or unfavorable pH levels alter an enzyme's 3D shape and destroy its function, a process called this.

What is denaturing?

500

Regulatory molecular stop-and-go signals in the cell cycle that verify whether a cell is ready to proceed to the next phase.

What are checkpoints?
