ATP is often called the energy 'currency' of the cell. What do the letters ATP actually stand for?

What is Adenosine Triphosphate?

100

This green pigment found inside plant cells is responsible for absorbing sunlight to power photosynthesis.

What is chlorophyll?

100

While photosynthesis stores energy in glucose, cellular respiration does the opposite by breaking down glucose to release this type of cellular energy molecule

What is ATP?

100

 "Because fermentation happens entirely without oxygen, it is given this scientific name, which means 'without air

What is anaerobic?

100

Often called the basic building block of life, all living organisms are made of one or more of these.

What is a cell?

200

ATP is made of three main parts: a nitrogenous base called adenine, a 5-carbon sugar called ribose, and a chain of how many phosphate groups?"

What is three?

200

Photosynthesis doesn't just happen anywhere—it takes place inside this specific, oval-shaped green organelle

What is the chloroplast?

200

Cellular respiration kicks off with a stage called Glycolysis, where glucose is chopped in half. Surprisingly, this first step doesn't happen in the mitochondria at all—it happens out here in this fluid of the cel

What is the cytoplasm?

200

When you are sprinting hard and your muscle cells run out of oxygen, they switch to fermentation and produce this specific byproduct, which makes your muscles feel like they are burning.

What is lactic acid?

200

In a eukaryotic cell, this large central organelle acts as the brain, protecting and storing the cell's DNA.

What is the nucleus?

300

To release energy for cellular work, a chemical bond must be broken. Energy is released from ATP when this specific bond is snapped off

What is the bond between the second and third phosphate groups?

300

Photosynthesis is split into two main stages. This first stage takes place in the thylakoid membranes and absolutely requires solar energy to split water molecules

What are the light-dependent reactions

300

"Because the main stages of cellular respiration in the mitochondria require oxygen to run, it is given this specific scientific name meaning 'with oxygen

What is aerobic?

300

Yeast cells perform a different kind of fermentation. They produce carbon dioxide gas and this substance, which is used to make bread rise and create certain beverages.

What is alcohol fermentation

300

This famous double-helix molecule contains the genetic instructions used in the development and functioning of all living organisms.

What is DNA?

400

 ATP loses a phosphate group and releases its energy, it becomes a lower-energy molecule with only two phosphates, known by this 3-letter abbreviation

What is ADP?

400

Named after the scientist who discovered it, this second stage of photosynthesis takes place in the stroma and uses carbon dioxide to build glucose

What is the Calvin Cycle?

400

Once inside the matrix of the mitochondria, the broken-down pieces of glucose enter this famous, continuous cycle that releases carbon dioxide and charges up electron carriers

What is the Krebs Cycle?

400

Without oxygen, the mitochondria shuts down. Because of this, fermentation only yields a tiny amount of energy per glucose molecule—specifically, this exact number of ATP.

What is 2 ATP?

400

This flexible outer layer surrounds all cells, deciding exactly what gets to enter and leave to maintain homeostasis.

What is the cell membrane?

500

While ATP is known for storing energy, biologically speaking, it belongs to this specific macromolecule group because it is made of a sugar Phosphate and base.

What is a Nucleic Acid?

500

During the light reactions, water ($H_2O$) is split apart. The hydrogen ions are kept for energy, but this gas is released into the atmosphere as a 'waste product'—which is lucky for us, since we need to breathe it

What is oxygen

500

This grand finale stage of cellular respiration takes place on the inner membrane (cristae) of the mitochondria and produces the absolute most ATP—around 32 to 34 molecules

What is the Electron Transport Chain?

500

Fermentation itself doesn't actually make any ATP at all! Its entire structural purpose is to recycle electron carriers so that this initial, cytoplasm-based step of cellular respiration can keep running over and over again.

What is Glycolysis?

500

Proteins are the workhorses of the cell. This specific type of protein acts as a biological catalyst, speeding up chemical reactions without being used up
