How do muscle cells access what they need to keep producing energy
Ganezh [65]

Muscle cells access what they need to continue producing energy through chemical energy from ATP to transform it into mechanical energy.  

Muscle cells are elongated cells whose length can reach several centimeters.  

The muscle uses ATP (energy) to carry out conformational changes in its molecular structure => variation in the length of the sarcomere.  

Adenosine triphosphate (ATP) is the basic source of energy for muscle contraction.  

Each link stores 7300 calories of energy per mole of ATP under normal conditions and when a phosphate radical is separated from the molecule, these calories are available providing the energy necessary for muscle contraction.  

The muscle cell has three mechanisms to resynthesize ATP:  

  • ATP synthesis through phosphocreatine.  

  • Anaerobic glycolysis process with the transformation of muscle glycogen into lactate.  

  • From oxidative phosphorylation.  

ATP synthesis through phosphocreatine consists of the transfer of energy from phosphocreatine to ADP so that it can reincorporate a phosphate group to its molecule and transform it into ATP.

So the energy that has been released in the hydrolysis of PCr is directly used to resynthesize ATP from ADP.  

Therefore, we can conclude that muscle cells access what they need to continue producing energy through the chemical energy of ATP to transform it into mechanical energy.

A moss is in the gametophyte phase of its life cycle. Which of the following best describes what happens next in the moss’s life
nekit [7.7K]

Answer:

Male and female gametes are formed and combine in a moist environment to form a zygote.

Explanation:

The gametophyte of a moss plant bears male sex organ antheridia and female sex organ archegonia.

Sperms, the male gametes are produced within antheridia and the eggs are produced in archegonia.

Both the antheridia and archegonia may be produced on the same gametophyte or separate gametophytes depending on the type of moss.

Haploid sperms are released from the antheridia and with the help of moisture, it reaches to a haploid egg in an archegonium. The female gamete or egg is fused with sperm to produce a diploid zygote.

The zygote later develops into the diploid sporophyte.
