What is the chemical equation for photosynthesis?
6CO2 + 6H2O -> C6H12O6 + 6O2

Help in photosynthesis
Produce energy (ATP) through cellular respiration
Store genetic information
How is energy transferred within a cell from glucose to ATP?
Via osmosis
Through photosynthesis
Through a series of enzymatic reactions in glycolysis, citric acid cycle, and oxidative phosphorylation.
By direct diffusion
What is the role of NADH and FADH2 in cellular respiration?
NADH and FADH2 are produced during the Krebs cycle in cellular respiration.
NADH and FADH2 inhibit the electron transport chain in cellular respiration.
NADH and FADH2 donate electrons to the electron transport chain for ATP production.
NADH and FADH2 are used for energy storage in cellular respiration.
What is the primary function of the Krebs cycle in cellular respiration?
Facilitate protein synthesis
Produce glucose
Generate ATP
Regulate cell division
What are the end products of the Krebs cycle?

Glucose, water, oxygen
Glycerol, fatty acids, ketone bodies
ATP, NADH, FADH2, carbon dioxide
How do plants obtain the carbon dioxide needed for photosynthesis?
Through their roots
From the air through their stems
Through stomata on their leaves
By absorbing it from the soil
