Unit 3 Flashcards

1
Q

Cellular Respiration Formula

A

C6H12O6 + 6O2 → 6CO2 + 6H2O + ENERGY
Glucose + Oxygen = Carbon Dioxide + Water + ATP

Q

Mitochondria structure

A
  • two membranes (outer and inner)
  • inner membrane is folded up
  • innermost portion called the matrix

Q

What would happen if decomposition didn’t occur?

A

Carbon would be trapped inside dead organisms, leaving less carbon dioxide for photosynthesis, and resulting in a pile up of dead organisms

Q

What is a Light Dependent Reaction

A
  • Occurs in the thylakoid of the chloroplast.
  • Chlorophyll is the light acceptor.
  • Water is split to make O2

Q

What is a Light Independent Reaction (Calvin cycle)

A
  • Occurs in the stroma of the chloroplast
  • Carbon fixation allows for CO2 to be used to make glucose.
17
Q

What is the photosynthesis formula?

A

6CO2 + 6H2O + SUNLIGHT → C6 H12O 6 + 6O 2
Carbon Dioxide + Water + Sunlight = Glucose + Oxygen

18
Q

Photosynthesis

A
  • Energy from sun
  • Carbon dioxide taken in
  • Oxygen given off
  • Happens in chloroplast
  • ONLY IN PLANTS
19
Q

Cellular Respiration

A
  • Energy from sugar
  • Carbon dioxide given off
  • Oxygen taken in
  • Happens in mitochondria
  • Occurs in plant & animal cells
20
Q

Aerobic

A

Occurs with oxygen

21
Q

Anaerobic

A

occurs without oxygen
- alcohol fermentation
- lactic acid fermentation
