All life depends on the availability of usableenergy. This energy is released when
(1) organisms convert solar energy into thechemical energy found in food molecules(2) respiration occurs in the cells of producersand high-energy molecules enter the atmosphere(3) cells carry out the process of respiration(4) animal cells synthesize starch and carbondioxide

What is a living thing?
• Imagine that you are space traveler who lands on an unknown planet. How could you determine if what you are looking at is alive.

Key Concepts
• Metabolism – all the chemical activities an organism must carry on to sustain life.
• Homeostasis – the maintenance of a stable internal environment in spite of changes in the external environment.
![Page 14: LIFE PROCESSES](https://reader030.vdocuments.us/reader030/viewer/2022033106/568164d4550346895dd7074e/html5/thumbnails/14.jpg)
Nutrition
• ingestion - obtaining food from the environment
• digestion (processing food for use by the organism).
• egestion (removal of solid wastes)
![Page 15: LIFE PROCESSES](https://reader030.vdocuments.us/reader030/viewer/2022033106/568164d4550346895dd7074e/html5/thumbnails/15.jpg)

TRANSPORT
• Ability to absorb and circulate materials to the cells.
– Oxygen absorbed into the bloodstream– Oxygen circulated to the cells– Oxygen absorbed into the cell
![Page 19: LIFE PROCESSES](https://reader030.vdocuments.us/reader030/viewer/2022033106/568164d4550346895dd7074e/html5/thumbnails/19.jpg)

RESPIRATION• The process of releasing energy
• Glucose (blood sugar) is broken down, and the energy released is stored as ATP.
• Energy released by the compound ATP is used to perform life functions.
![Page 21: LIFE PROCESSES](https://reader030.vdocuments.us/reader030/viewer/2022033106/568164d4550346895dd7074e/html5/thumbnails/21.jpg)
RESPIRATION• Plants and animals use the oxygen in
the air to turn food into energy.

RESPIRATION
• Human Respiratory System

EXCRETION
• Removal of cell waste from the organism.
• Exhaling, Urinating, Sweating
• Wastes include water, carbon dioxide, salts, and nitrogen.

SYNTHESIS
• small molecules combine to form larger ones.
• Photosynthesis– CO2 + H2O + sunlight = C6H12O6 + O2
![Page 28: LIFE PROCESSES](https://reader030.vdocuments.us/reader030/viewer/2022033106/568164d4550346895dd7074e/html5/thumbnails/28.jpg)
SYNTHESIS
• Combining 2 glucose molecules to make a larger maltose molecule
![Page 29: LIFE PROCESSES](https://reader030.vdocuments.us/reader030/viewer/2022033106/568164d4550346895dd7074e/html5/thumbnails/29.jpg)
GROWTH• An increase in size
– increases in cell size– Increase in cell number.
• The raw materials for growth are the products of synthesis.
