250

Plants absorb this gas from air through stomata to use as a main reactant in photosynthesis.

What is carbon dioxide? (CO2)

250

Photosynthesis produces and releases this gas, which animals and plants inhale for cellular respiration.

What is oxygen? (O2)

250

This 6-carbon simple sugar is the main chemical energy molecule made by plants during photosynthesis.

What is glucose? (C6H12O6)

250

This main source of radiant energy allows the initial stage of photosynthesis in autotrophic organisms.

What is light energy?

250

Roots absorb this liquid compound from the soil so plants can perform photosynthesis

What is water? (H2O)

350

In the light-independent reactions, this gas is attached to RuBP during the first step of organic sugar creation.

What is carbon dioxide? (CO2)

350

During the light-dependent reactions of photosynthesis, oxygen is created when this specific molecule is split in the thylakoid space.

What is Water? (H2O)

350

Cellular respiration begins by breaking down one molecule of glucose into two molecules of pyruvate during this.

What is glycolysis?

350

Light energy is absorbed by this green pigment found in the thylakoid membranes of chloroplasts.

What is chlorophyll?

350

At the end of cellular respiration, water is formed when oxygen accepts electrons and protons at this mitochondrial protein complex network.

What is the electron transport chain?

500

In cellular respiration, carbon dioxide is released as a waste byproduct during pyruvate oxidation and the following cyclic pathway.

What is the Krebs cycle?

500

In aerobic cellular respiration, oxygen has what role at the very end of the electron transport chain.

What is the final electron acceptor?

500

During the Calvin cycle, it takes this many turns of the cycle to assemble one complete molecule of glucose.

What is six?

500

When light hits photosystems inside the thylakoid membrane, it boosts these subatomic particles to a higher energy level to start the light reactions.

What are electrons?

500

Other than releasing oxygen, the splitting of water during the light reactions provides positively charged ions that build a proton gradient across the thylakoid membrane.

What are hydrogen ions? (or H+ protons)
