Answer: The correct answer would be lactic acid fermentation.

Explanation:

In humans, specially in muscle cells, lactic acid fermentation takes place during high intensity exercise. During exercise when oxygen supply fails to meet the demands of muscle, they undergo lactic acid fermentation instead of cellular respiration.

During this process, the pyruvate (end product of glycolysis) is converted into the lactate with the help of enzyme lactate dehydrogenase.

It regenerates NAD⁺ lost in the glycolysis and thus, helps in continuous working of glycolysis.

A spaceship is traveling to the moon. Both the moon and the earth pull on the spaceship during the entire trip. At a point much

Artist 52 [7]

The reason that the ship gets pulled on the whole time is because Both planets well Planet and moon have a gravitaional pull, without them they would collide with each other. Its common sense that if you closer to the moon the moon has a greater affect on your with its gravity, thats why you must be closer to the moon in order for the moon to pull you closer in! :) Hope this helps!

Why does active transport take place in the small intestine during absorption of food molecules? I thought it was only diffusion

dezoksy [38]

Well if the small intestine needs to absorb the nutrients, then the nutrients kind of have to go somewhere right?
also, there is a transfer from high to low
inside the small intestine there are lots of nutrients that need to be absorbed to be made into energy
the cells would only have to take in more nutrients if it has run out, aka it's low on nutrients
thus the high concentration outside the cell and the low concentration inside leads to the active transport through the cell membrane

The trp and lac operons are regulated in various ways. How do bacteria regulate transcription of these operons? Sort the stateme

OLEGan [10]

Answer:

Operon is not transcribed:

-lac operon: lactose absent

-trp operon: tryptophan present

Operon is transcribed, but not sped up through positive control:

-lac operon: lactose and glucose present

-trp operon: tryptophan absent

Operon is transcribed quickly through positive control:

-lac operon: lactose present, glucose not

Explanation:

The trp operon is controlled via negative control only.

Presence of tryptophan will inhibit the transcription of the operon genes

The lac operon is controlled via negative control and positive control.

●Negative control:

--Transcription is turned off due to

active Repressor protein and absence of lactose

--Transcription is turned on due to

Inactive Repressor protein and presence of lactose

●Positive control:

--Transcription rate is higher due to absence of transcription and presence of lactose as a regulatory protein (CAP) adhere to the lac operon promoter
