Biology
1 answer:
Leto [7]3 years ago
6 0

Answer: If you are 80 years and older, it should be less than 150/90 (“150 over 90”). In general, the lower your blood pressure, the better. A blood pressure reading of less than 90/60 is normal as long as you feel okay.

Imagine that you are a hungry cell and find a large supply of citrate (citric acid). how many atps can you get from each citrate
lakkis [162]
This question is asking for the number of ATP that is produced by the citric acid cycle and the electron transport chain. 
Citrate is the first biological substance in the citric acid cycle and it is the starting point of the cycle. From one molecule of citrate, the citric acid cycle will produce 2 ATP while the electron transport chain will produce 34 ATP. Therefore, together both the citric acid cycle and the electron transport chain will produce 36 ATP.

Is the following an example of a. Negative feedback loop b. Positive feedback loop Hydrochloric acid and pepsin are enzymes secr
Finger [1]

Answer:  This is a positive feedback loop.

Explanation:

The protein digestion in the body is an example of the positive feedback. The gastric secretions is stimulated chiefly by the action of three chemicals.

These chemicals are acetylcholine, histamin and gastrin. These chemicals stimulate the parietal cells to secrete HCL and intrinsic factors.

The chief cells secrete pepsinogen in response to the gastrin and ACh. As the dietary proteins are digested, it breaks down the amino acids and peptides.

This stimulates the G cells of the stomach to secrete more gastrin. This is how the positive feedback loop for the protein digestion works.

Which two cellular organelles in eukaryotes have both electron transport systems and chemiosmotic mechanisms?
aalyn [17]

Answer:

Mitochondria and the chloroplast

Explanation:

Electron transport refers to the transfer of of electrons from electron donors to electron acceptors via a reduction-oxidation reaction.  

In the mitochondria the process is called Oxidative phosphorylation whereas in the Chloroplast it is called Photo-phosphorylation since it utilizes light.

Chemiosmotic mechanisms allow the movement of ions across a semi-permeable membrane down their electrochemical gradient.

In both mitochondria and chloroplast,have these mechanisms for the production of ATP .
