Cellular Energy
Essential Question.
Activating strategy
How are the cellular processes photosynthesis and cellular respiration related to each other and essential for the survival of organisms?
How we are solar powered? I think we use solar cells. Also by the sun
What is ATP?
1.
Plants get there energy from the ____sun______.
2. Through the process of _________photosynthesis___________.
3. Animals get there energy from _______food________.
Why do we need energy?
_to move, run, eat, sleep, and metabolism_
Why do cells need energy?
- to move molecules during transport
- cell division
- move proteins
- move cilia and flagella
- to maintain homeostasis
What do cells use for energy? ATP
Unit Backbone # of phosphate groups

How does the cell get to the energy in ATP? Bond between the 2 nd and 3 rd phosphate is broken and the energy is released
Is ATP recycled? Yes or No
What is photosynthesis? The process which plants make glucose and oxygen from carbon dioxide, water and sunlight.

Photosynthesis is broken down into __2__ stages.
Photosynthesis equation is:

The three materials for photosynthesis are:
1. sunlight is trapped by the pigment chlorophyll in the chloroplast
2. water is taken in by roots
3. carbon dioxide is taken in by the stomata on the underside of the leaves
The products for photosynthesis are:
1. oxygen is breathed out by the plans through the stomata
2. glucose is stored in the plant and only obtained by eating the plant
Photosynthesis occurs in the _______chloroplast _____ of a cell.
Chlorophyll is the pigment in the chloroplast gives the plant its green color.
Three factors that affect photosynthesis rates:
a. amount of water
b. light intensity
c. temperature
Cellular respiration is the process in which cells turns _____glucose_______ into energy for running cellular activities.
Cellular respiration occurs in ____2___ stages.
Cellular respiration equation:
The first stage of cellular respiration occurs in the ____cells cytoplasm__________ by the _______lysosomes _________.
It is a ____anaerobic ___ process called glycolysis.
It produces ___2___ ATP.

Where does the 2 nd stage of cellular respiration occur? Occurs in the mitochondria.
The 2 nd stage is aerobic or anerobic? This means ___aerobic no oxygen ____.
A total of ___36__ ATP are produced during cellular respiration.
Fermentation is also known as ____aka

anaerobic respiration_________.
Fermentation occurs when _____oxygen________ is not available. This means it is an aerobic/anaerobic.
Two types of fermentation are:
a. alcoholic- energy, alcohol and carbon dioxide are the product
b. lactic acid- energy and lactic acid are the products. ( 2 ATPs produced)
Occurs in humans when need more energy than oxygen being breathed in
Humans use _____lactic acid___ fermentation when they no longer have enough oxygen for cellular respiration.
Items Aerobic Anaerobic
