What is the connection between photosynthesis and cellular 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 similarities and differences between cellular respiration and photosynthesis?
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 2 differences between photosynthesis and cellular 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.
Which characteristics do photosynthesis and cellular respiration have in common?
Both processes involve a cycle of chemical reactions. Both processes involve energy conversions. Both processes use and produce ATP. Both processes use an electron transport chain.
What is the relationship between photosynthesis and cellular respiration quizlet?
What is the relationship between photosynthesis and cellular respiration? Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food.
What is the role of oxygen in photosynthesis and in cellular respiration quizlet?
cellular respiration, because it shows the flow of energy from plants to animals. What roles does oxygen play in photosynthesis and in cellular respiration? Photosynthesis releases oxygen into the atmosphere as a. product, whereas cellular respiration uses oxygen as a reactant to release energy from food.
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 is the relationship between photosynthesis and cellular respiration?
What will be made by one glucose molecule in the presence of oxygen?
In aerobic conditions, the process converts one molecule of glucose into two molecules of pyruvate (pyruvic acid), generating energy in the form of two net molecules of ATP.
What is the main source of energy for cellular respiration?
glucose
Which two molecules are needed for cellular 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.
Where does the glucose needed for cellular respiration come from in humans?
Cellular respiration in humans starts in the digestive and respiratory systems. Food is digested in the intestines and converted to glucose. Oxygen is absorbed in the lungs and stored in red blood cells.
Where does the glucose for respiration come from?
This energy comes from glucose. All animals and humans get glucose through eating it, but plants need to make their own glucose during photosynthesis. Plants and animals transport glucose and oxygen to tiny structures in their cells, called mitochondria. Here, the glucose and oxygen take part in a chemical reaction.
In which two locations does cellular respiration occur?
Key Terms
| Term | Meaning |
|---|---|
| Mitochondria | The eukaryotic cell structure where cellular respiration occurs |
| Cytoplasm | The contents of a cell between the plasma membrane and the nuclear envelope; includes cytosol which is the jelly-like substance that fills the space between organelles |
| Aerobic | Process that requires oxygen |
How does glucose affect cellular respiration?
During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
What is the major purpose of the glucose in cellular respiration?
Glucose provides quick energy for cells. Fat has more energy than glucose, but it requires some chemical conversions before we can get it into the process of cellular respiration, so it takes longer to use.
What are three alternatives to glucose based cellular respiration?
There are three alternatives to cellular respiration, including anaerobic respiration, alcohol fermentation, and lactic acid fermentation. Organisms such as methanogens (archaea), sulfur-reducing bacteria, and yeasts commonly prefer these alternatives to produce metabolic energy.
What are the three products of cellular respiration?
Cellular respiration is this process in which oxygen and glucose are used to create ATP, carbon dioxide, and water. ATP, carbon dioxide, and water are all products of this process because they are what is created.
What is produced through cellular respiration?
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
What goes in the mitochondria during cellular respiration?
Mitochondria Function Cellular respiration is the process of making ATP using the chemical energy found in glucose and other nutrients. In mitochondria, this process uses oxygen and produces carbon dioxide as a waste product.
What are some examples of cellular respiration?
Types of Cellular Respiration. Below are examples of aerobic respiration and anaerobic cellular respiration: lactic acid fermentation and alcoholic fermentation.
Why does cellular respiration occur in steps?
Cellular respiration actually “burns” glucose for energy. However, it doesn’t produce light or intense heat like burning a candle or log. Instead, it releases the energy slowly, in many small steps. The energy is used to form dozens of molecules of ATP.
What is the difference between digestion and cellular respiration?
Digestion breaks down food to release energy, so cellular. respiration can produce additional energy for the body. sugars from the food are broken down during respiration to. provide energy for the body.
