WORTH 100 POINTS why does catalase need to be in an alkaline environment

2 answers:

6 0

Catalase is an enzyme, a large protein that speeds up the rate of a chemical reaction. The optimum pH level of catalase is between pH 7 and pH 11. At a pH level lower or higher than this range, the catalase stops working.

7.Storage of materials and support of the cell

8.Contractile vacuoles pump excess water out of the cell, while other types of vacuoles hold materials inside of cells

10.Lysosomes breakdown large molecules and waste without them clutter could accumulate in the cell, which has been linked to serious human diseases

13.Ribosomes are small particles of RNA and protein found throughout the cytoplasm. They are involved in synthesis of proteins.

14. Endoplasmic reticulum

15.Ribosomes are found on the surface of rough ER. Smooth ER has no ribosomes on its surface.

16.The Golgi apparatus is like a customization shop in a factory. It puts the finishing touches on proteins before they leave the factory.

17.If the cell manufactures proteins that are normally released to travel to other cells. Those cells would not receive the proteins. The loss of these proteins might cause the "receiver" cells to function poorly.

25.regulates

27.Vesicles transport newly synthesized proteins to the Golgi apparatus. After the Golgi apparatus modifies the proteins, vesicles transport the modified proteins to the cell membrane, where they are released.

Why do some cells appear in one type of cell but not in another ?

Ivahew [28]

This is because cells are not only characterized by their genetic material and other interior components but also by genes they express cells have to fulfill multiple different functions to be able to build complex multicellular organisms

Which characteristic of bacteria makes them efficient transgenic organisms to produce insulin or other medicines?

emmainna [20.7K]

The characteristic of bacteria that makes them efficient transgenic organisms to produce insulin or other medicines is they readily accept new genetic material.

<h3>What do you mean by Transgenic organisms?</h3>

Transgenic organisms may be defined as an organism whose genome has been modified by the insertion of one or more foreign (non-self) DNA sequences from another species via artificial means.

A Plasmid is a circular DNA that assists in the insertion of foreign DNA sequences into the bacterial cell.

Therefore, the characteristic of bacteria that makes them efficient transgenic organisms to produce insulin or other medicines is they readily accept new genetic material.

If the atp synthase for an organism contains 15 c subunits, how many protons must flow through atp synthase per each new atp tha

anastassius [24]

Each time a new ATP is created, ATP synthase must process 5 protons.

<h3>Where is ATP synthase found and what does it do?</h3>

ADP and phosphate are converted into ATP by the mitochondrial enzyme ATP synthase, which is located in the inner membrane.
Protons are transported over a gradient created by electron transfer from the chemically positive to the negative side of the proton, which drives the flux of protons.

<h3>How does photosynthesis's ATP synthase function?</h3>

The light-driven production of ATP is catalyzed by the chloroplast ATP synthase, which is activated in the light and deactivated in the dark by redox-modulation via the thioredoxin system.
This down-regulation is thought to be crucial for minimizing wasted ATP hydrolysis at night.

<h3>What makes ATP synthase so crucial?</h3>

All cellular functions are powered by ATP, which is constantly used by cells and required for production. About 100 ATP molecules can be produced by each ATP synthase every second.
