Cellular Respiration

Cellular Respiration Intro

Mrs. Nebzydoski

Think....

Can you answer these questions?​

What is consumed in cellular respiration?

What is produced in cellular respiration?

Cellular Respiration Equation

Cellular Respiration Reaction

Note:

Reactants= one C₆H₁₂O₆ and six O₂

Products= six CO₂ and six H₂O and ATP energy

Multiple Choice

The reactants of cellular respiration are (choose all that apply)

• glucose

• oxygen

• carbon dioxide

• water

• energy

Multiple Choice

The products of cellular respiration are (choose all that apply)

• glucose

• oxygen

• carbon dioxide

• water

• ATP Energy

Multiple Choice

Cellular respiration occurs in which organelle?

• chloroplast

• nucleus

• mitochondria

Cellular Energy from Redox Reactions

• Look at page 92, Figure 6.5 A

• The equation shows that glucose loses H's

• The equation shows that oxygen gains H's

• We refer to H's in regard to electrons

• This is a Redox Reaction

Oxidation Reduction Reactions

We say Leo the lion goes Ger

Lose electrons = oxidation

Gain electrons = reduction

NAD+ and NADH

Look at Figure 6.5B on page 92

​

NAD is what we call an "electron carrier"

​

We focus on this molecule throughout the process of cellular respiration

Multiple Choice

Oxidation is the _____ of electrons.

(Hint: LEO the lion goes GER)

• loss

• gain

Multiple Choice

NAD+ becomes NADH when it picks up two ______.

• electrons

• protons

• glucose molecules

• ATP molecules

Steps of Cellular Respiration

• Glycolysis

• Pyruvate Oxidation

• Kreb's Cycle (citric acid cycle)

• Oxidative Phosphoryllation (e- transport chain)

Can you explain where these stages happen?

• Glycolysis

• Citric Acid Cycle

• Oxidative Phosphorulation

For the test:

• Be able to explain glycolysis

• Be able to explain the citric acid cycle

• Be able to describe the electron transport chain and oxidative phosphoryllation

• Be able to describe the structure of a mitochondria​
