Chapter 9: How do cells harvest energy?
Just as cars need fossil fuels to power their engines, the living cells that make up our bodies use food as a fuel source. To harness the energy in food every cell in our bodies contains microscopic biological machines, known asmitochondria, which convert food molecules into energy. Although ...
The energy is ___ makes the cells able to do their work.A.that B.which C.what D.suchHow to choose,translate and why?Thanks.
Why does a cell perform fermentation if it does not produce any ATP energy for the cell? Describe how ATP synthase produces ATP via chemiosmosis. What is the net ATP yield for bacteria? How do cells use the ATP cycle? a. Cells use the cycle primarily to generate heat. b. Cells use th...
Are water and carbon dioxide the only ingredients to make energy? How do plants make energy?Answer and Explanation: Hello! photosynthesis = carbon dioxide (CO2)+ water (H2O)+ energy (solar) = sugar(C6H12O6)+ oxygen (O) cell respiration = sugar +oxygen = carbon...
What is a vitamin, and why do we need to take them every day? How do poisons work? What does it mean to be alive, at least at the cellular level? All of these questions have obvious answers once you understand how cells work -- so let's get started!
These enzymes do everything from breaking glucose down for energy to building cell walls, constructing new enzymes and allowing the cell to reproduce. Enzymes do all of the work inside cells.1 2 3 4 … 14 Share: Print | Citation More Awesome Stuff Medicine Cipro Overview Life Science ...
1. PV cells absorb incoming sunlight The photovoltaic effect starts with sunlight striking a photovoltaic cell. Solar cells are made of a semiconductor material, usually silicon, that is treated to allow it to interact with the photons that make up sunlight. The incoming light energy causes electr...
How much energy can we get from the Sun? What are solar cells? How are solar cells made? How do solar cells work? How efficient are solar cells? Types of photovoltaic solar cells How much power can we make with solar cells? Power to the people Why hasn't solar power caught on yet?
We could, for example, use solar cells to do the electrolysis of water "for free," but we could just as easily store the same energy in batteries and use those to power our cars instead. Fuel-cell cars sound promising, but if battery cars really are better, hydrogen may turn out to ...
