Summary Introduction

To determine:

The number of primary and secondary spermatocytes produced if a single ejaculation contains about 240 million sperm cells.

Introduction:

The process of the formation of motile spermatozoa from the non-motile primary spermatocyte cell is known as spermatogenesis. The process of spermatogenesis in males initiates at puberty. The primary spermatocyte is diploid in origin and is responsible for the production of motile sperms. The mature sperms or spermatozoa are haploid.

Biology Question
✓ Details Draw a protein that is embedded in a membrane (a transmembrane protein), label the lipid bilayer and the protein. Identify the areas of the lipid bilayer that are hydrophobic and hydrophilic. Draw a membrane with two transporters: a proton pump transporter that uses ATP to generate a proton gradient, and a second transporter that moves glucose by secondary active transport (cartoon-like is ok). It will be important to show protons moving in the correct direction, and that the transporter that is powered by secondary active transport is logically related to the proton pump.
drawing chemical structure of ATP. please draw in and label whats asked. Thank you.
