Biology of Cells

Why are photosynthetic organisms like algae so important?

• Algae can capture the energy of the sun and convert it into forms of energy

• They are not important

• Can convert sunlight into energy and release oxygen as a byproduct

• They attack inasive species.

Energy transformation is not efficient.

• True

• False

Which of the following is correct?

• Autotrophs capture and transform the energy of sunlight by photosynthesis.

• Heterotrophs capture and transform the energy of sunlight by photosynthesis

• Heterotrophs obtain energy by eating other organisms.

• Autotrophs obtain energy by eating other organisms.

What is the Photosynthesis Chemical Equation?

• Sun+Water+CO2 -> O2+C6H12O2

• Sun+Water+CO2 -> O2+C6H4O6

• Sun+Water+O2 -> CO2+C6H12O6

• Sun+Water+CO2 -> O2+C6H12O6

How do algal biofuels compare to other fuels in terms of costs, benefits, and sustainability?

• They don't

• Photosynthetic algae convert fructose into energy-rich oils

• Photosynthetic algae convert glucose into energy-rich oils

• Cleaner energy

What are the three macronutrients our bodies need?

• Proteins, fatty acids, carbs.

• Proteins, amino acids, carbs

• Proteins, fats, carbs

When does fermentation come into play?

• When the electron transport chain has no oxygen & aerobic respiration stops

• When the electron transport chain has oxygen

• When the electron transport chain has no oxygen

• When the electron transport chain has oxygen and aerobic respiration stops.

Glycolysis occurs in the absence of
