Unit 8- Lesson 4 (Aerobic Respiration)

L4-Aerobic Cellular
Respiration

Multiple Choice

Aero is Greek for Air, what do you think Aerobic Respiration requires (input)?

• Oxygen

• Carbon Fiber

• ATP

• Water

What is cellular respiration?

• Cellular respiration is a process that

releases chemical energies from sugars
and other carbon-based molecules to
make ATP (energy)

• Cellular respiration can be an aerobic

process (it needs oxygen) to take place, or
an anaerobic process (it doesn’t need
oxygen) to take place

Multiple Choice

The prefix An means not, when would Anaerobic Respiration take place?

• No Oxygen

• So much oxygen

• Cells are too busy for aerobic Respiration.

• During Photosynthesis

Where does aerobic respiration

occur?

• Aerobic cellular respiration

takes place in plants, animals,
fungi, protists, and SOME
bacteria
– Aerobic respiration occurs

mainly in themitochondria

• Remember: Cells cannot make

ATP directly from food

• Food must be broken down

into smaller molecules, such
as glucose

mitochondrion

animal
cell

Multiple Choice

Which is correct?

• Food-> Glucose-> ATP

• Glucose-> Food-> ATP

• ATP-> Food-> Glucose

• ATP->ADP->Food

Mitochondrial Structure

Multiple Choice

Mitochondria has DNA, what other organelle has DNA inside?

• Nucleus

• Ribosome

• Vacuole

• Chloroplast

Multiple Choice

Where does the Carbon in C6H12O6 (Glucose) come from?

• Carbon Dioxide

• Oxygen

• Carbon Fibrils

• ATP

Equation for Aerobic Respiration

• The equation for the overall process is:

C6H12O6 + 6O2 →6CO2 + 6H2O + 38 ATP

• INPUTS: glucose (sugar), oxygen

• Where does the C6H12O6 come from? food

• Where does the O2 from? atmosphere

• OUTPUTS: carbon dioxide, water, ATP

• Where does the CO2 go? atmosphere

• Where does the H2O go? atmosphere/ground

• Where does the ATP go? cellular processes

Multiple Choice

Where does Aerobic Respiration take place?

• Mitochondria

• Nucleus

• Chloroplast

• Cytoplasm

The 3 Processes

Three Processes involved

1. Glycolysis

2. Krebs Cycle (Citric Acid Cycle)

3. Electron Transport Chain (ETC)

Total ATP yield= 38

Multiple Choice

• 2; Cytoplasm

• 34; Mitochondrial Matrix

• 34; Cytoplasm

Electron Transport Chain (ETC)

• Where does it

occur? Inner
membrane of
mitochondria

• # ATP

produced= 34
ATP

Multiple Choice

Electron Transport Chain (ETC) creates _____ ATP in the ________

• 34; Inner Mitochondrial Membrane

• 34; Mitochondrial Matrix

• 2; Inner Mitochondrial Membrane

• 2; Mitochondrial Matrix

Overview:

• What:

– Aerobic Cellular Respiration

• Where:

– Mitochondria

• Why:

– ALL cells need energy (ATP)

• How:
C6H12O6 + 6O2→→6CO2+ 6H2O + 38 ATP
