Cellular Respiration Lesson

Cellular Respiration

… the release of energy from food

Photosynthesis Overview

• Sunlight energy converts carbon dioxide (CO₂) and water (H₂O) into oxygen (O₂) and glucose (C₆H₁₂O₆).

Photosynthesis

Photosynthesis: takes place in 2 stages:
1. Light dependent stage
2. Light independent stage/ Calvin cycle

​Stroma
(light independent reaction takes place here. CO₂ is taken in and C₆H₁₂O₆ is released.)

​Thylakoids
(light dependent reaction takes place here. H₂O is split up and oxygen is released)

Multiple Choice

What happens during the LIGHT DEPENDENT reaction?

• chloroplast splits to form electron carriers

• carbon dioxide is absorbed and oxygen is released

• water is split and oxygen is produced

Multiple Choice

What happens during the LIGHT INDEPENDENT reaction/ Calvin Cycle?

• chloroplast splits to form electron carriers

• carbon dioxide is absorbed and glucose is released

• water is split and oxygen is produced

Why do we eat?

It takes place in the mitochondria - the
“Powerhouse” of a cell. ALL living cells
carry out cellular respiration.

3

● Mitochondria are round or

rod-shaped organelles with a
double membrane.

● A mitochondrion is often

called a “powerhouse of the
cell" because it produces
energy for the cell.
Mitochondria convert
chemical energy in sugar to
usable energy for the cell.
This energy is known as ATP.

CELL ORGANELLES

Cells

Mitochondria

​Cristae are finger-like structures inside the mitochondria

​Matrix is the liquid inside the mitochondria

​Intermembrane space

ATP: Adenosine Triphosphate is a nucleic acid in the same family as DNA and RNA.

​Oxygen + Glucose --> Carbon dioxide + Water + ATP

ATP: is a high energy
molecule released
from food by the
process of cellular
respiration. It can be
used by the body for
active processes and
the molecule ADP is
formed.
