What are the 2 metabolic pathways a cell can use and what determines which pathway is being used?
Cells can use aerobic (oxidative) and anaerobic (glycolytic) pathways. The availability of oxygen determines which pathway is being used; aerobic pathways are utilized in the presence of oxygen, while anaerobic pathways are used when oxygen is limited. Oxygen is essential for the electron transport chain in aerobic metabolism, while glycolysis can proceed in the absence of oxygen.

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 happens second in the metabolic sequence?
The second step in the metabolic sequence depends on the pathway being considered. In general, after digestion and absorption, carbohydrates are broken down into glucose, which enters glycolysis as the second step in cellular respiration.
Do Second-order neurons of ascending sensory pathways always decussate.?
No! Only neurons of the specific (lemniscal) & non-specific (anterolateral) pathways decussate and sensation is therfore interpreted in the opposite cerebral hemisphere.Spinocerebellar ascending pathways transmit proprioceptive sensory stimuli to the same side of the cerebellum.
What is the difference between De novo and salvage pathway of nucleotide synthesis?
In De Novo pathways, the nucleotide bases are assembled from simpler compounds. The framework for a pyrimidine (= thymine and cytosine or uracil) base is assembled first and then attached to ribose. The framework for a purine (= adenine and guanine) base is synthesized piece by piece directly onto a ribose-based structure. In salvage pathways, performed bases are recovered and reconnected to a ribose unit. To put it even simpler; in De Novo pathways, the bases of the nucleotides are made from scratch by using simpler starting materials (including amino acids). For this process, ATP hydrolysis is required. Salvage pathways recycle already used bases by reattaching them to a ribose. I hope this information helps answering your question!
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 catalyst in a metabolic pathway?
A catalyst in a metabolic pathway is typically an enzyme that speeds up the rate of a specific chemical reaction without being consumed in the process. Enzymes achieve this by lowering the activation energy required for the reaction to occur, allowing metabolic processes to proceed efficiently within 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 happens second in the metabolic sequence?
The second step in the metabolic sequence depends on the pathway being considered. In general, after digestion and absorption, carbohydrates are broken down into glucose, which enters glycolysis as the second step in cellular respiration.

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 does PFK mean?
PFK can refer to phosphofructokinase, an enzyme involved in glycolysis, a metabolic pathway that converts glucose into energy. It can also stand for People for Kids, an organization that focuses on advocating for children's rights and well-being.
What is the pathway of food being digested?

Which court determines guilty or not guilty?
Whichever court you are being tried in determines your sentence.
Where can you find enzymes and how do they function in biological processes?
Enzymes are found in cells and are essential for biological processes. They act as catalysts, speeding up chemical reactions in the body without being consumed in the process. Enzymes help break down food, build proteins, and regulate various metabolic pathways in living organisms.
