Answer: Option A
Explanation: The cardiovascular system is the system of human body which circulates blood through the complete body to supply oxygen to the whole body.
It also carries nutrients along with the blood and carries waste materials from the body to the heart.
Heart rate can be defined as the number of times the heart beats per minute and it is related to the load the heart has.
The sympathetic nervous system of the body releases hormone like epinephrine, nor epinephrine which increases the heart rate. There are many other factors that increase the heart rate such as exercise, stress et cetera.
Two protons are translocated across the inner mitochondrial membrane by complex iv for every pair of electrons passing through the electron transport chain.
<h3>What is
inner mitochondrial membrane?</h3>
- The mitochondrial membrane that divides the intermembrane gap from the mitochondrial matrix is known as the inner mitochondrial membrane (IMM).
- As a result, the inner mitochondrial membrane maintains the proton gradient that powers oxidative phosphorylation and serves as a functional barrier to the passage of tiny molecules between the cytosol and the matrix.
- Cristae are the name for the inner membrane folding of mitochondria.
- They broaden the surface.
- The inner or cytoplasmic membrane controls the flow of nutrients, metabolites, macromolecules, and information into and out of the cytoplasm and preserves the proton motive force necessary for energy storage.
- It is impermeable to polar molecules.
- The inner membrane of E is connected to more than 100 distinct proteins.
- Similar to the cell membrane, the mitochondrial inner membrane is mostly composed of a phospholipid bilayer.
- Several proteins that function to carry out the electron transport chain are embedded in this bilayer.
- The membrane's surface area is increased by folds called christae.

Answer:
Step 2: The right ventricle pumps the oxygen poor blood to the lungs via pulmonary valve. Step 3: The left atrium receives oxygen -rich blood and pumps it to the left ventricle. Step 4: The left ventricle pumps the oxygen-rich blood via aortic valve, submitting this blood through the entire body.

i think it’s the last one on question number one, and the first one on question two.
