What are the 3 most important energy-carrier molecules in a cell? What are their overall jobs?

Biology
1 answer:
Simora [160]4 years ago
3 0

Answer:

<em>Three important energy carrier molecules in a cell are: ATP (Adenosine triphosphate, NADPH (Nicotinamide Adenosine Dinucleotide Phosphate) and FADH2. </em>

Explanation:

All the three carrier molecules play an important role in cellular respiration and photosynthesis. One NADH molecule is equal to 3 ATP molecule while 1 FADH2 molecule is equal to 2 ATP molecule.

During the active process, ATP is used as a form of energy because ATP dephosphorylates to ADP and Inorganic phosphate, Pi and release energy.

irina1246 [14]

Answer:

true

Explanation:

Cerebrospinal fluids  is a  colorless fluid  that is secreted in the choroid plexus,and  circulates in the ventricles system  and sub -aranchinoid space  of the brain and spinal cord. its provides nutrients  to the surrounding  neurons, cushions the effects of trauma, pressure, acts as buffer and provides protection through immune  system .

it plays a vital role in regulating  blood flow, through a process called cerebral auto regulation,This is needed to maintain efficient cerebral blood flow of oxygen and other metabolites, and withdraw of metabolic wastes from the brain.

in order to analyze it to diagnose some neurological diseases  its sample is usually taken out in a process called lumbar  puncture.

HURRY!! PLEASE HURRY!
diamong [38]

Explanation:

cost

  • ongoing maintenance
  • initial design and construction​

benefit

  • protection of infrastructure
  • lower insurance costs
  • employment opportunities

The flood mitigation projects have initial startup costs and ongoing maintenance costs over the years. However, apart from the costs, these have additional benefits like lower insurance costs due to protected infrastructure and  reduced flood damage, along with employment opportunities during building and maintenance.

Further Explanation:

Flooding usually happens when lots of rainfall occurs in relatively short time periods. These are usually enough to cause rivers to overflow their banks and also occur when storms force large volumes of water from the ocean to travel inland.  Typically these occur in arid ecosystems, having low average rainfall- the water accumulates in dry regions and saturates the area. This phenomena are majorly destructive and can uproot trees, destroy bridges, buildings and other infrastructure while leading to loss of life.

If glucose is not the energy of the cell, what is? how does glucose relate to this?
mote1985 [20]

Answer:

Adenosine triphoshate(ATP) is the energy currency of the cell.

Explanation:

Glucose is the Stored energy which is formed by the Glycogen. At the time when the energy is required glycogen is converted into glucose while, ATP is the energy which is ready to use. In aerobic conditions, Glucose produces about 30 ATP molecules. ATP molecule consists of HIGH ENERGY PHOSPHATE BONDS which are broken down when energy is required.

<u><em>ADP + inorganic phosphate (pi)</em></u><em>forms</em><u><em> ATP</em></u>
