Answer:
3 (Cells carry out the respiration process)
Explanation:
Cellular respiration is a metabolic (catabolic) process common to all living things as all living things need energy for their life processes.
Respiration is the biochemical process in which the cells of an organism obtain energy by breaking down organic molecules in presence or absence of oxygen (aerobic or anaerobic) resulting in the release of Carbondioxide (CO2), water and Adenosine triphosphate (ATP).
Food molecules (containing stored energy in their chemical bonds) absorbed after digestion are broken down and the energy within their molecules are freed. This freed energy in form of ATP, is used to power the organism's movement and physiological functions.
Note that, ATP is an energy carrying molecule and a usable form of energy by cells. This is so because ATP releases energy quickly. Energy is released from ATP when the end phosphate (Pi) is removed to become ADP (adenosine diphosphate), which is a low energy molecule.
Aerobic cellular respiration consists of Glycolysis, Kreb's cycle and Oxidative phosphorylation. A total of 38 ATP molecules is produced in the cytosol of prokaryotes while a total of 36 ATP molecules is produced in the mitochondria of eukaryotic cells.
Answer:
The lipid bilayer.
Explanation:
It is a thin polar membrane made of two layers of lipid molecules. These membranes are flat sheets that form a continuous barrier around all cells.
Answer: Cushing Syndrome
Explanation:
Cushing Syndrome occurs when the body is exposed to high level of cortisol for a long time either externally (taken into the body from outside ) or internally (secretion in excess of the hormone called cortisol by the body) . It can also be called hypercortisolism .
The symptoms of Cushin Syndrome may vary depending on the severity of the excess cortisol secretion. Females may have irregular menstrual period due to this condition.
Asthma and arthritis patients who take corticosteroids and experiences the mentioned symptoms should seek medical attention for diagnosis.
