Summary Introduction
To review:
The events that produce four normal heart sounds and the one that can be heard with the help of a stethoscope.
Introduction:
The heartbeat or heart sounds are generated during a cardiac cycle as blood flows through the different chambers of the heart. The sounds so produced can be heard through a stethoscope. These sounds are referred as ‘lubb’ and ‘dubb’, which signifies efficient functioning of heart.

- Biology Questionarrow_forward✓ 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.arrow_forwarddrawing chemical structure of ATP. please draw in and label whats asked.
