What is the advantage of using a metabolic pathway to burn glucose?
1. the energy is released gradually, which allows a significant amount of the released energy to be conserved for the cell to use rather than being lost as heat. 2. additionally, the process generates intermediate compounds into the metabolic pathways (divert surplus intermediate compounds into the metabolic pathways that best meet the organism's constantly changing needs)
What are some examples of feedback inhibition?
an excess of a product of one reaction causes the enzyme of another reaction to stop working.
What determines whether an embryo will become male or female?
In humans, gender is determined by the x and y chromosomes, with xx being a genetic female and xy being a genetic male
What is a type of protein or RNA molecule that speeds up metabolic reactions in plants and animals without being permanently changed or destroyed?
Enzymes are biological catalysts that speed up metabolic reaction rates by lowering the reaction's activation energy. Proteins and RNA molecules can both function as enzymes.
Which is capable of being reduced during either glycolysis or the Krebs cycle?
NAD+ is capable of being reduced during both glycolysis and the Krebs cycle. It helps in passing energy from glucose to other pathways in the cell.

Why a river pathway is not straight?
Rivers tend to flow into the lowest ground that they contact, while being deflected by higher ground. So the shape of the landscape determines the pathway of a river, and landscapes do not tend to be linear.
What are the features of sympathomedullary?
There are two pathways. 1) Sympathetic Pathway where the hypothalamus sends information to the brain stem and it travels down the spine to the adrenal medullar. Then, adrenaline and noradrenaline are released which effectively causes the heart rate and blood pressure to rise as oxygen is being released to the muscles 2) Parasympathetic Pathway: reverses the effects of the Sympathetic pathway. So the heart rate and blood pressure returns to normal.
What pathway converts privates into lactate?
The pathway that converts pyruvates into lactate is actually part of the PA pathway. The total result of the PA pathway is to convert pyruvates into acetate, with conversion to lactate being one of the reactions along the way.
What are some examples of feedback inhibition?
an excess of a product of one reaction causes the enzyme of another reaction to stop working.
What is the pathway of food being digested?
Here is the pathway of food being digested in a listed order:List in chronological order:1.mouth2.pharynx3.esophagus4.stomach5.small intestine6.large intestine7.rectum
Which court determines guilty or not guilty?
Whichever court you are being tried in determines your sentence.
What is an example of a semicolon being used inappropriately?
Walking along a pathway; I tripped and fell.
What is the CHEMISTRY of baking?
There's a lot of chemistry involved in baking. For instance, you might be using yeast and sugar in your dish. Yeast is a type of fungi that is able to convert the sugar you add into ethanol and carbon dioxide via what is known as a metabolic pathway. Metabolic pathways are the concern of biochemistry. I suppose that you're using heat. In order to create a flame, you need a fuel (e.g. liquefied petroleum gas, wood, etc), a heat source (to start things up), and oxygen in order to produce heat, carbon dioxide, water vapor and a host of other products. The reaction itself is the subject of inorganic chemistry (and if you wanted to know how much heat was being produced, you would call upon physical chemistry to work its magic).
How do you identify the criteria that determines a substance as being a hazardous material?
identify the criteria that determines a substance as being a hazardous material
What is blood clotting?
There are the intrinsic and extrinsic pathways in clotting. The intrinsic pathway is initiated when blood comes in contact with damaged endothelium or collagen, and involves clotting factors XII, XI, IX, and VIII. The extrinsic pathway is activated when being exposed to tissue factor from tissue injury or the addition of thromboplastin to blood, and involves clotting factor VII. The two pathways meet at the point of clotting factor X activation to lead the final common pathway. From here, factor X is converted to prothrombin, prothrombin to thrombin, thrombin to fibrinogen, fibrinogen to fibrin, and finally fibrin to fibrin clot. Platelets, activated by thrombin, adhere to the damaged endothelium wall or collagen to form a plug. At the same time, they activate clotting factors VII and X. More platelets are stimulated by fibrin clots, resulting in reinforcing the formed clots.
What determines the size and shape of a loop of the roller coaster?
by it being big
