Fermentation is
an anaerobic process in which energy can be released from glucose even
though oxygen is not available. Fermentation occurs in yeast cells, and a form of fermentation takes place in bacteria and in the muscle cells of animals.
Cellular respiration, like burning, results in the complete oxidation of glucose into CO2 and water. Fermentation, on the other hand, does not fully oxidize glucose. Instead, small, reduced organic molecules are produced as waste. As a result, cellular respiration
releases more energy from glucose than fermentation
.
– Cellular respiration is the process that releases energy from food in the presence of oxygen. …
Photosynthesis releases oxygen into the atmosphere
, and cellular respiration uses that oxygen to release energy from food. – In the absence of oxygen, fermentation releases energy from food molecules by producing ATP.
What are four similarities between photosynthesis and cellular respiration?
Photosynthesis and cellular respiration are two biochemical processes that are essential to most life on Earth. Both of these processes involve multiple complex steps and many of the same molecules—oxygen (O

), carbon dioxide
(CO

), water (H

O), glucose (C

), and adenosine triphosphate (ATP)
.
What are the 2 types of fermentation?
There are two types of fermentation,
alcoholic fermentation
Why does fermentation occur?
Fermentation occurs
in the absence of oxygen (anaerobic conditions)
, and in the presence of beneficial microorganisms (yeasts, molds, and bacteria) that obtain their energy through fermentation. … Fermented foods contain the enzymes required to break them down. Fermentation also aids in pre-digestion.
What are the similarities and differences between photosynthesis and cellular respiration?
Cellular respiration takes place in the mitochondria of cells. While photosynthesis requires energy and produces food,
cellular respiration breaks down food and releases energy
. Plants perform both photosynthesis and respiration, while animals can only perform respiration.
What are the similarities between cellular respiration and respiration?
Both processes involve
taking in oxygen and removing carbon dioxide
, and we need both to survive. However, breathing is a macroscopic process and only ships the oxygen and carbon dioxide around the body. Cellular respiration is a microscopic process, taking place in the cells.
What are the similarities between photosynthesis and aerobic respiration?
Photosynthesis and aerobic respiration are both part of
a cyclic process of biochemical reactions
. Photosynthesis requires the products of aerobic respiration (carbon dioxide and water), while aerobic respiration requires the products of photosynthesis (glucose and oxygen).
What are the benefits of fermentation give examples?
Fermentation is the breakdown of carbs like starch and sugar by bacteria and yeast and an ancient technique of preserving food. Common fermented foods include kimchi, sauerkraut, kefir, tempeh, kombucha, and yogurt. These foods may
reduce heart disease risk and aid digestion, immunity, and weight loss
.
What are the steps in fermentation?
Lactic acid fermentation has two steps:
glycolysis and NADH regeneration
.
What are examples of fermentation?
- Beer.
- Wine.
- Yogurt.
- Cheese.
- Certain sour foods containing lactic acid, including sauerkraut, kimchi, and pepperoni.
- Bread leavening by yeast.
- Sewage treatment.
- Some industrial alcohol production, such as for biofuels.
Where does fermentation occur?
Fermentation reactions occur in
the cytoplasm of both prokaryotic and eukaryotic cells
. In the absence of oxygen, pyruvate does not enter the mitochondria in eukaryotic cells.
What does fermentation start with?
Fermentation begins with
glycolysis
which breaks down glucose into two pyruvate molecules and produces two ATP (net) and two NADH. Fermentation allows glucose to be continuously broken down to make ATP due to the recycling of NADH to NAD+.
What are the end products of fermentation?
The products are of many types:
alcohol, glycerol, and carbon dioxide
from yeast fermentation of various sugars; butyl alcohol, acetone, lactic acid, monosodium glutamate, and acetic acid from various bacteria; and citric acid, gluconic acid, and small amounts of antibiotics, vitamin B
12
, and riboflavin (vitamin B
2
) …
What is the major difference between photosynthesis and cellular respiration as shown here?
The main difference between photosynthesis and cellular respiration is that
photosynthesis is an anabolic process
, where the synthesis of organic compounds occurs, storing energy whereas cellular respiration is a catabolic process, where the stored organic compounds are utilized, producing energy.
