active transport occurs in cells for example when Na-k pump is at work.Any process that involves active transport most often inv
vekshin1

Answer:

Any process that involves active transport most often involves the​ expenditure of energy in the form of ATP hydrolysis.

Explanation:

Active transport in cells is a form of transport which involves the transport of solute molecules across a membrane against a concentration gradient using energy provided from some chemical reaction occuring in the cell.

Active transport is an endergonic (energy-requiring) process and therefore, must proceed only when coupled to an exergonic (energy-releasing) process such as the breakdown of ATP, an oxidation reaction, absorption of sunlight, etc.

In many instances in cell, such as the Na/K pump, ATP hydrolysis is the the common exergonic reaction to which active transport is coupled to.

Identify the parts of the female and male reproductive system and their functions. ​
Lena [83]

<u><em>Female:</em></u>

*Ovaries - release of oocytes (eggs), estrogen and progesterone.

*Oviducts (fallopian tubes) - where fertilization of the oocyte occurs to form a zygote.

*Uterus - where the zygote develops

*Cervix and vagina - allow for the entry of sperm for fertilization

<u><em>Male:</em></u>

*Testes - Releases testosterone and sperm

*Vas deferens - Passageway for sperm

*Epididymis - allows the sperm to pass from the testes and vas deferens and equips them with semen so they can survive internal fertilization

*Penis - releases sperm into the external environment for fertilization to occur

I hope I helped!
