What are the products of the first stage of respiration?
Stage one. Glucose in the cytoplasm of cells is broken down into two molecules of pyruvate . This releases enough energy to produce two molecules of ATP for every molecule of glucose that is broken down.
Is the first step of breathing?
The first step in this process is breathing in air, or inhaling. Inhalation means bringing air rich in oxygen into the body. The second step is gas exchange in the lungs where oxygen is diffused into the blood and the carbon dioxide diffuses out of the blood.
What are the 7 steps of cellular respiration in order?
Overview of the steps of cellular respiration. Glycolysis. Six-carbon glucose is converted into two pyruvates (three carbons each). ATP and NADH are made….
- Pyruvate oxidation.
- Citric acid cycle.
- Oxidative phosphorylation.
What are the three steps to cellular respiration?
The reactions of cellular respiration can be grouped into three main stages and an intermediate stage: glycolysis, Transformation of pyruvate, the Krebs cycle (also called the citric acid cycle), and Oxidative Phosphorylation.
What are the 3 steps of cellular respiration and where does each occur?
Cellular respiration is the process in which cells break down glucose, release the stored energy, and use it to make ATP. The process begins in the cytoplasm and is completed in a mitochondrion. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.
What is formula for cellular respiration?
Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O.
What is difference between photosynthesis and respiration?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
What are the formulas for photosynthesis and respiration?
The chemical equation for photosynthesis is 6CO2 + 6H2O + energy C6H12O6 + 6O2. The chemical equation for respiration is C6H12O6 + 6O2 6CO2 + 6H2O + energy.
What is the correct equation for photosynthesis?
Photosynthesis is usually represented by the equation 6 CO2 + 6 H2O + light –> C6H12O6 + 6 O2. During this process, organisms such as plants go through the light-dependent and light-independent reactions to convert carbon dioxide and water into sugars and oxygen.
What is the similarities of 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 (O2), carbon dioxide (CO2), water (H2O), glucose (C6H12O6), and adenosine triphosphate (ATP).
What are 3 differences between photosynthesis and respiration?
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.
Does photosynthesis produce ATP?
The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.
What are the reactants in respiration?
Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
Which type of respiration produces more ATP?
What is the name of respiration which utilizes oxygen?
Respiration using oxygen to break down food molecules is called aerobic respiration .
Where does respiration happen in a cell?
The mitochondria , found in the cell cytoplasm, are where most respiration happens.
Does fermentation require oxygen?
When oxygen is not present or if an organism is not able to undergo aerobic respiration, pyruvate will undergo a process called fermentation. Fermentation does not require oxygen and is therefore anaerobic. One type of fermentation is alcohol fermentation.
What are the 3 types of fermentation?
What Are the 3 Different Types of Fermentation?
- Lactic acid fermentation. Yeast strains and bacteria convert starches or sugars into lactic acid, requiring no heat in preparation.
- Ethanol fermentation/alcohol fermentation.
- Acetic acid fermentation.
What is needed for fermentation?
Fermentation is the reaction that is used to produce alcohol from sugar. It is an anaerobic reaction, which means it requires no oxygen to be present other than the oxygen atoms contained in the sugar. The other ingredient required for the reaction to take place is yeast.
What are 3 examples of foods made using fermentation?
There are thousands of different types of fermented foods, including:
- cultured milk and yoghurt.
Is water needed for fermentation?
Water for fermentation Water is the most important ingredient used in fermenting. It may seem like you can just turn on your tap and get clean water to use, but with fermenting foods, it isn’t that easy. Many things in water can affect how well foods ferment and can also affect the taste.
What are the 2 types of fermentation?
There are two types of fermentation: lactic acid fermentation and alcoholic fermentation.
