How does the lac operon help E. coli conserve energy and other resources?

Biology
1 answer:
konstantin123 [22]3 years ago
3 0

Answer:

A lac operon is a group of three genes that are always transcribed together which code proteins needed for the metabolism of lactose. ... This way of transcription control preserves the energy of E. coli, so proteins that these bacteria need in presence of lactose aren't synthesized when this molecule is absent.

How do cells release <br> Energy in the process of cellular respiration
White raven [17]

Answer:

Explanation:

There are two types of respiration:

1. Aerobic respiration  

2. Anaerobic respiration

Aerobic respiration

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Glucose + oxygen → carbon dioxide + water + 38ATP

Anaerobic Respiration

It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.  

Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide

This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration
