ATP is produced in all stages of cellular respiration. Which two statements describe the process of ATP synthesis in the electro
n transport chain? A. The ATP synthase spins when the hydrogen ions rush past, acting as a "matchmaker" and grabbing another phosphate group to attach to an ADP molecule.
B. The high concentration of NAD+ acts as a catalyst to speed up the formation of ATP from ADP.
C. The high concentration of hydrogen ions in the intermembrane space allows them to diffuse across the membrane into the matrix.
D. The FADH2 synthase spins as the high-energy electrons rush past, synthesizing ATP from ADP.
In each cell, through a process of gene expression, DNA is transcripted into mRNA which are templates used to create different proteins resulting in different functions in your body.
Mammals, insects, fish and plants all have different systems of exchanging gas. For mammals we breathe into our lungs, for fish they use gills and insects use spiracles.
The reason for Ovum being the correct answer, is because the Ovum is in the lower plant structure, and is the structure that is needed to be fertilized to reproduce gametes.
