<span>The question is asking us to fill in the gaps in the following sentence: When a person loses consciousness due to a head injury from a car crash, the (gap) keeps the body functioning by regulating the flow of information between the brain and the rest of the body. The best answer is that the gap should be filled by "autonomous nervous system" - this system is the one that is not controlled consciously, but one that is working in the background to make sure our body functions work properly.</span>
A normal heart rate ranges between 60-100 beats per minute. The higher the heart rate is, the faster the blood is pumping through the heart. When exercising a persons heart will be higher because the brain and the muscles in the body are in need of oxygen so the heart needs to pump faster in order to sustain optimal performance.<span />
Answer:
A,C E
Explanation:
The inner membrane of the mitochondria separate the matrix of the mitochondria from the cytosol(inner membrane space.). It is invaginated folded inwards to form the critae. This is an adaptive feature to increase the surface area for biochemical reaction in the mitochondria.
The invagination gives two compartments the inner mitochondria also creates the outer intermembrane space and the inner matrix
These are the substances that can pass freely the inner membrane of the mitochondria.Pyruvate and H+ can not pass through.Specifically,it is not preamble to H+ because, hydrogen ions are needed to generate the electrochemical gradients needed for the chemical energy for phosphorylation of ADP by P to form ATPs by the enzyme ATPase synthase.If the inner membrane is permeable to H+ the electochemical gradient will not be produced, and therefore ATPs productions stops.
O2 needs to pass through the inner membrane because it it the final electron acceptor. Therefore if not allowed to pass through oxidative phosphorylation and ETC will nor occur.
CO2 must pass through because its accumulation will increase the acidity of the inner mitochondria
