What is the main fuel source for the work of the cell Brainly?

What is the main fuel source for the work of the cell Brainly?

Answer Expert Verified The energy currency of the cells is ATP. This is used for example in photosynthesis where plant cells produce food and oxygen using carbon dioxide and glucose for the consumers. ATP is also used widely in all other cycles to produce different products.

What is the main energy source that fuels all cell processes?


What 3 things are required for glycolysis to begin what 3 things are produced?

Glycolysis starts with one molecule of glucose and ends with two pyruvate (pyruvic acid) molecules, a total of four ATP molecules, and two molecules of NADH.

How long do fuel cells last?

The fuel cell stacks are designed to last the lifetime of the vehicle, about 150,000–200,000 miles. At the end of its lifespan, the fuel cell will be disassembled and the materials recycled, similar to what happens with vehicle components today.

What is a disadvantage of fuel cells?

Disadvantages of using fuel cells in cars fuel cells and electric motors are less durable than petrol engines and diesel engines, so they are not so long-lasting. fuel cells are very expensive. some methods of producing the hydrogen fuel release carbon dioxide and other pollutants into the atmosphere.

Do fuel cells go bad?

Fuel cells have a finite life span. The environment can greatly affect the cell’s longevity. The typical lifespan of a fuel cell is between 8 and10 years, although all sanctioning bodies limit use to 5 years from the date of manufacture.

Will fuel cells replace batteries?

To meet these future needs, portable fuel cells, called micro-fuel cells, have the potential for replacing conventional batteries. However, micro-fuel cells, once commercialized, hold the promise for providing more back up ‘green power’ at lower cost than its competing battery technologies.

What are the problems with hydrogen fuel cells?

The two prime dangers from fuel cell and hydrogen-powered vehicles are the danger of electrical shock and the flammability of the fuel. Fuel cells power vehicles by electro-chemically combining hydrogen gas (H2) and oxygen (O2) from the surrounding air into water (H20) and electrical energy.

Why hydrogen is not used as a fuel?

Hydrogen has the highest calorific value so it can be considered as the best fuel but it is highly inflammable so it is diificult to store, transport and handle so it is used as a fuel only where it is absolutely necessary.

Are hydrogen cars better than electric?

However, as hydrogen cars densely pack their energy storage, they’re usually able to achieve longer distances. While most fully electric vehicles can travel between 100-200 miles on a single charge, hydrogen ones can get to 300 miles, according to AutomotiveTechnologies.

What are the two main problems with hydrogen fuel?

The key challenges include: Weight and Volume. The weight and volume of hydrogen storage systems are presently too high, resulting in inadequate vehicle range compared to conventional petroleum fueled vehicles.

Can hydrogen be used as cooking fuel?

In addition to these applications, hydrogen can also be used as a cooking fuel. In many developing economies, a high percentage of domestic energy demand is related to cooking, which primarily relies on fossil and biomass fuels.

Can you burn hydrogen in a gas stove?

The truth is hydrogen is relatively safe. We handle dangerous products every day and don’t think twice about it- gasoline, natural gas stoves, propane BBQ’s, welding & scuba cylinders, drain cleaners and electricity. Hydrogen is non-toxic and non-polluting. When we burn hydrogen, the only by-product is pure water.

Does hydrogen burn with a blue flame?

Hydrogen burns with a pale blue flame that is nearly invisible in daylight. A pure hydrogen flame will not produce smoke. Hydrogen flames have low radiant heat.

Can natural gas appliances run on hydrogen?

Hydrogen could be used in the existing natural gas system, either by blending with the natural gas or by converting the gas system completely to hydrogen. This has the potential to significantly reduce carbon emissions, if low carbon methods of producing hydrogen can be developed and delivered at scale.

What will replace gas boilers in 2025?

In 2025, gas boilers will be replaced by renewable heating systems in all new-build homes. This is part of a government effort to achieve net-zero CO2 emissions by 2050….There are many options to choose from, such as:

  • Heat pumps.
  • Heat networks.
  • Hydrogen boilers.
  • Electric radiators.

What is replacing oil and gas?

The main alternatives to oil and gas energy include nuclear power, solar power, ethanol, and wind power.

Is natural gas more expensive than electricity?

Natural gas is almost always cheaper than electricity. Gas appliances cost more upfront, but over time, gas will save you money on your utility bill.

What’s the cheapest way to heat a house?

The 7 Cheapest Ways To Heat A Home

  • Buy an energy-efficient space heater.
  • Buy a smart thermostat.
  • Use credit cards to pay your utility bills.
  • Sign up for budget billing.
  • Insulate your attic.
  • Invest in warm clothing.
  • Consider installing solar panels.

Which is cheaper to run gas or electric?

When it comes to electric heating running costs… On the face of it, the gas vs. electric heating cost is much cheaper. A single kilowatt-hour (kWh) unit of gas costs around 4p, whereas the average price for a kWh of electricity is more than 16p.

How much gas does it take to produce 1 MWH?

It would therefoe take about 7000 cubic feet of gas to produce one megawatt-hour. In the U.S. today, one thousand cubic feet of gas sells at wholesale for about US$7.00 (seven dollars.

How much gas does it take to produce 1 kWh?

Natural Gas & Oil Natural Gas: It takes 0.01003 Mcf (1,000 cubic feet) to make 1 kWh. This includes power plant inefficiency.

How much CO2 does a kWh of gas produce?

0.185 kg / kWh

How much electricity is produced from natural gas?

Natural gas was the largest source—about 40%—of U.S. electricity generation in 2020. Natural gas is used in steam turbines and gas turbines to generate electricity. Coal was the third-largest energy source for U.S. electricity generation in 2020—about 19%. Nearly all coal-fired power plants use steam turbines.

What is the most efficient energy source?

Most Efficient Energy Sources Although there are many types of energy, the most efficient forms are renewable: hydro-thermal, tidal, wind, and solar. Solar energy has been proven to be the most efficient and effective among renewable energy sources for home and commercial use.
