in what ways is ATP like a fully charged battery?

Answers

Answer:

ATP ATP can be compared to a fully charged battery because both contain stored energy, whereas ADP resembles a partially charged battery. Releasing Energy From ATP The energy stored in ATP is released when ATP is converted into ADP and a phosphate group.

Explanation:

The ATP molecule is comparable to a battery that can be recharged. It is ATP when ultimately charged. It's ADP when it's worn out. When the battery runs out, it is simply recharged rather than discarded.

What is ATP?

A vital "energy molecule" in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it is a coenzyme that transfers cells' energy by liberating its phosphate groups when it interacts with enzymes like ATP triphosphatase. The molecule comprises an adenine bicyclic system, a furanose ring, and a triphosphate chain.

The discovery of ATP was announced in 1929 by two research teams. It was isolated from mammalian muscle and liver by Cyrus H. Fiske and Yellapragada Subbarow at Harvard Medical School (Boston). Karl Lohmann discovered it in muscle tissues while working for the Kaiser Wilhelm Institutes in Berlin and Heidelberg.

Over the next 15 years, ATP separation from other sources came next. In 1987, Koscak Maruyama of Chiba University (Japan) provided a thorough analysis of ATP's discovery and structural elucidation.

Therefore, ATP is like a rechargeable battery because it can be recharged and discharged.

A. bacterial cell is much larger than an animal cell
B. bacterial cell has more mitochondria than an animal cell
C. bacterial cell has RNA for its genetic material, whereas an animal cell does not
D. a bacterial cell does not have membrane-bound organelles, whereas an animal cell does

Answers

Answer: It would be option D, "a bacterial cell does not have membrane-bound organelles, whereas an animal cell does." Bacteria cells are prokaryotic. This means that they have no membrane bound nucleus or membrane bound organelles whereas a plant or animal cell does.

The answer is D.) bacterial cells lack a cellular membrane unlike animal cells

How do nutrients move through an environment? What drives the movement of nutrients?

Answers

Answer:

The nutrient cycle is a system where energy and matter are transferred between living organisms and nonliving parts of the environment. This occurs as animals and plants consume nutrients found in the soil, and these nutrients are then released back into the environment via death and decomposition.

The nutrient cycle is a system that transfers energy and matter between living organisms and non-living elements of the environment.

How do nutrients move?As the concentration of nutrients around the root system decreases, nutrients from higher concentration areas diffuse - or move - toward low concentration areas and the roots. They only move a short distance, however. Potassium (K) and phosphorus (P) primarily move via diffusion.The nutrient cycle is a system that transfers energy and matter between living organisms and non-living elements of the environment. This occurs when animals and plants consume soil nutrients, which are then released back into the environment through death and decomposition.The movement of nutrients to the root surface in response to a concentration gradient is referred to as diffusion. When nutrients are found in higher concentrations in one area than in another, there is a net movement to the low-concentration area, resulting in equilibrium.

What is a Prokaryotic cell?

A prokaryotic cell may be defined as a type of cell which is present in prokaryotes. This type of cell typically lacks a well-defined nucleus and other membrane-bound cell organelles. Organisms like bacteria, archaea, etc. possess this type of cell.

All prokaryotes and eukaryotes have a cell membrane known as a Plasma membrane. Most prokaryotic organisms have a small amount of genetic material in the form of a single molecule known as circular DNA.

Protein synthesis is one of the essential functions of all cell types. Ribosomes are significantly found in every type of eukaryotic as well as prokaryotic organisms like bacteria.

Therefore, the presence of mitochondria is a characteristic that is only common to eukaryotic cells but is not found in prokaryotic cells.

Explanation:

All plants and animals are multicellular organisms. Plants are autotrophs, meaning they can make their own food (usually by photosynthesis). In contrast, animals rely on other organisms as a food source (are heterotrophs)

Fungi and protists are more variable. Protists are mostly small unicellular organisms, some perform photosynthesis to make their own food, others eat other organisms.

Fungi usually consume dead or decaying matter (decomposers)
