What is the overall reaction for cellular respiration quizlet?
C6H12O6 + O2 ——> CO2 + H2O + ATP.
How does a persons body continue to generate ATP when running a long distance race?
For short, quick bursts of energy, the body uses ATP already in muscles as well as ATP ► made by lactic acid fermentation. For exercise longer than about 90 seconds, cellular respiration is the only way to continue ► generating a supply of ATP.
Why do all organisms need food?
All living things need food to stay alive, grow, and get energy. Nutrition is the process by which living things get or make food. All animals get food by eating other living things.
What is a calorie briefly explain how cells use high calorie molecule such as glucose?
Briefly explain how cells use a high-calorie molecule such as glucose. A calorie is enough energy to heat one gram of water by one degree celsius. Cells use molecules such as glucose by breaking them down and using they energy they provide.
How are the processes of photosynthesis and cellular respiration connected quizlet?
Terms in this set (9) How are photosynthesis and cellular respiration connected? Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis.
How is heat involved in photosynthesis and respiration quizlet?
Heat is released in both photosynthesis and cellular respiration as a byproduct. The chemical reactions of photosynthesis occur in which cellular organelle?
Why do runners breathe heavily after a sprint race?
When the athlete runs in the race, his body needs more oxygen. His rate of breathing increases so that more oxygen can be supplied to the body. This is the reason, an athlete needs to breathe faster and deeper than usual; after finishing the race.
Why do I breathe heavy when running?
When we run, our carbon dioxide levels increase, triggering us to breathe more heavily. This means we need these precious deep breaths of oxygen to spur us on and give us the energy to keep going. When runners become used to running and start running longer and further, breathing while running becomes natural.
Why do living organisms need energy?
Inside every cell of all living things, energy is needed to carry out life processes. Energy is required to break down and build up molecules, and to transport many molecules across plasma membranes. All of life's work needs energy. A lot of energy is also simply lost to the environment as heat.
How do living things get energy?
Organisms use the stored energy in food to fuel all living processes. Food is organic molecules that serve as fuel and building material for all organisms. The breakdown of food molecules enables cells to store energy and to carry out the many functions of the cell and therefore the entire organism.
What are the different energy molecules in the cell describe the energy storage capacity of each and relate this to their function in living organisms?
ATP and Energy Molecules: Describe the energy storage capacity of each and relate this to their function in living organisms. ATP – stores smaller amounts of energy that is easily accessible by the cell. ATP is used to run all cell activities. Glucose – stores larger amounts of energy that is more difficult to access.
How do cells use high energy molecule such as glucose?
Cells use high-calorie molecules such as glucose in a process called cellular respiration. During cellular respiration, oxygen is required. Once a glucose molecule is broken down, there are 36 ATP molecules that are produced.
What is a difference between fermentation in human muscles and fermentation in yeast?
What is a difference between fermentation in human muscles and fermentation in yeast? In human muscle cells lactic acid is produced, while yeast produces ethyl alcohol.
How does the relationship between gas exchange in photosynthesis and cellular respiration influence the composition of the atmosphere?
While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis (Figure below) and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels.
Is the process of cellular respiration exothermic or endothermic explain your answer?
Is the process of cellular respiration exothermic or endothermic? Exothermic; energy is released as heat and ATP.
What is the relationship between photosynthesis and aerobic cellular respiration quizlet?
What is the relationship between photosynthesis and aerobic cellular respiration? Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis.
Why do we gasp after running?
The primary reason this happens is due to the buildup of carbon dioxide in the body. As carbon dioxide levels accumulate in the body from exercise, it triggers us to breathe more rapidly via our respiratory system. This allows more oxygen to be taken in.
Why do athletes hold their breath?
Breath holding also improves psychological preparedness and willpower as it helps an athlete to tolerate strong feelings of breathlessness, an important factor for sprint performance.
Is chest pain while running normal?
You might be surprised to learn that chest pain is actually more common in athletes than it is in sedentary people. “Luckily, in young athletes, it typically isn't a sign of heart trouble,” says sports cardiologist Tamanna Singh, MD. A medical evaluation can help you be sure.
Why do I cough after I run?
Simply stated, your airways temporarily constrict, which can cause you to cough. This is referred to as exercise-induced bronchoconstriction (EIB), according to the American College of Allergy, Asthma, and Immunology (ACAII).
How do different organisms get energy?
Organisms acquire energy by two general methods: by light or by chemical oxidation. Productive organisms, called autotrophs, convert light or chemicals into energy-rich organic compounds beginning with energy-poor carbon dioxide (CO2). These autotrophs provide energy for the other organisms, the heterotrophs.
How does the flow of matter differ from the flow of energy through an ecosystem?
As energy moves through an ecosystem, it changes form, but no new energy is created. Similarly, as matter cycles within an ecosystem, atoms are rearranged into various molecules, but no new matter is created.
Which organism receives the least amount of energy and why?
The top consumer of a food chain will be the organism that receives the least amount of energy.
Why is energy reduced at each level of the energy pyramid?
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
What are some different energy storage molecules in the cell?
ATP and Energy Molecules: ATP – stores smaller amounts of energy that is easily accessible by the cell. ATP is used to run all cell activities. Glucose – stores larger amounts of energy that is more difficult to access. Glucose is used for energy storage.
How does a molecule of ATP compare to a molecule of glucose in terms of the amount of energy stored?
A single molecule of glucose stores more than 90 times the energy stored by ATP. However, ATP, which transfers energy quickly, is used by the cell as an immediate source of energy.
Why do cells use fat and starch for long term energy storage instead of ATP molecules?
Why do cells use fat and starch for long-term energy storage instead of ATP molecules? It is hard to break down fat in a short amount of time, but it is very easy to breakdown ATP in a short amount of time. ATP is short-term, while fat is long-term.
What molecules carry these high potential energy?
What molecules carry these high potential energy electrons? NADH and FADH2 carry these high potential energy electrons.
Why does fermentation produce less ATP?
Fermentation produces less ATP than cellular respiration because a. NAD+ is regenerated by alcohol or lactate production, without the electrons of NADH passing through the electron transport chain.
How is cellular respiration observed in the process of wine fermentation?
In the absence of oxygen, fermentation allows the first step of cellular respiration to continue and produce someATP. The sugars in grapes are fermented to produce wine, which is then fermented to produce wine. The sugars are the starting materials for the process of glycolysis.
