Fermentation, Photosynthesis, Osmosis, Essay, Research Paper

This paper is on the processes of fermentation, cellular respiration,

photosynthesis, diffusion, osmosis, and enzyme activity. What do these

six processes have in common?

Fermentation is a chemical process that breaks down organic

materials. This process is carried out by such microbes as bacteria,

molds, and yeasts. For example, molds or fungi act upon mixtures of

molasses and mineral salts to produce penicillin. Yeast breaks down

sugar gotten from malted grain into ethyl alcohol and carbon dioxide gas

for use in beer. Sugar from grape juice is broken down in the same way

for use in wine. Fermentation also is essential in the production of

bread, cheese, and yogurt. In some cases, fermentation can be

unhealthy. For example of fermentation being unhealthy is that

fermented milk turns sour. You can get sick from sour milk.

Cellular respiration is when oxygen is used in chemical reactions

within the cells. These reactions release energy and produce carbon

dioxide and water as waste products. Cellular respiration is the source of

energy used to maintain life. energy in respiration is released, and

reactants of respiration is glucose. Two products of respiration are

CO2., and H2O.

Photosynthesis is a food making process that forms in green plants.

Photosynthesis is the chief function of leaves. The word photosynthesis

means putting together with light. Green plants use energy from light to

combine carbon dioxide and water to make food. All our food comes

from this important energy-converting activity of green plants. Light

energy is converted to chemical energy and is stored in the food that is

made by green plants. Animals eat the plants, and we eat animal

products as well as plants. In photosynthesis energy is stored, and

reactants of photosynthesis are CO2, and H2O. Glucose is produced by
