Which of the characteristics describe energy-carrier molecules?
can be coupled to energy-requiring reactions within a cell to help drive the reactions forward
accumulate in large quantities within a cell for long-term storage of energy
are quickly broken down once the molecules release their energy
include molecules, such as ATP, that contain high-energy chemical bonds
are generated when macromolecules, such as proteins, are broken down

Answers

Answer:

are quickly broken down once molecules release their energy

Explanation:

The characteristics of energy-carrier molecules are that they are quickly broken down once the molecules release their energy, which isoption. Energy-carrier molecules, like ATP, are quickly broken down into ADP (adenosine diphosphate) and inorganic phosphate (Pi) once they release their energy.

 Energy-carrier molecules, such as ATP, store energy in high-energy chemical bonds. When these bonds are broken, energy is released and can be used for cellular processes.Energy-carrier molecules are not typically generated when macromolecules, such as proteins, are broken down. Energy carriers like ATP are produced through cellular respiration, primarily in processes such as glycolysis, the Krebs cycle, and oxidative phosphorylation.

How would a scientist describe the illustrations showing the bones of a whale flipper and a bat
wing?
Vestigial structures because they will lose their function over time

Homologous structures because the structures are similar but have different functions

Analogous structures because they are similar but have different functions.

Embryonic structures because they show up before the species matures.

Answers

The bones of a whale flipper and a batwing are homo-logous structures because the structures are similar but have different functions. They have a common origin.

What are homo-logous structures?

Homo-logous structures can be considered as similar structures that have the same evolutionary origin but may or not have the same function.

Homo-logous structures are always present in a common ancestor of the species that have these structures.

Conversely, analogous structures have the same function but they do not exhibit a common origin.

Describe the currents that form along the equator.

Answers

Large rotating currents that start near the equator are called subtropical gyres. ... The process that creates deep currents is called thermohaline circulation—“thermo” referring to temperature and “haline” to saltiness. It all starts with surface currents carrying warm water north from the equator.

The currents that form along the equator are known as equatorial currents. These currents are driven by the trade winds and the Earth's rotation, creating a unique circulation pattern in the ocean.

There are two main equatorial currents:

Equatorial Counter Current: This current flows eastward along the equator, opposing the direction of the trade winds. North Equatorial Current and South Equatorial Current: These currents flow westward on either side of the equator.

The equatorial currents play a significant role in redistributing heat across the ocean and influencing climate patterns.

Thus, the equatorial currents along the equator are dynamic and essential components of the global ocean circulation system, playing a crucial role in the Earth's climate system.

Answers

photosynthesis takes place in chloroplasts. cellular respiration takes place in mitochondria

Photosynthesis occurs in chloroplasts and cellular respiration occurs in mitochondria.

What do you mean by cellular respiration?

Cellular respiration is the process by which biological fuels are oxidised in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, to drive the bulk production of ATP.

Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body.

Cellular respiration takes place in both the cytosol and mitochondria of cells. Glycolysis takes place in the cytosol, whereas pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation occur in the mitochondrion.

the golgi body interacts the most with which of these
A.nucleus
B.free ribosomes
C.Nucleolus
D.endoplasmic reticulum

Answers

D. The Endoplasmic Reticulum

When it comes to the processing and classification of proteins within the cell, the endoplasmic reticulum (ER) and the Golgi apparatus (also known as the Golgi body or Golgi complex) most often interact. Therefore, the correct option is D.

Before being delivered to their final cellular locations, proteins made by ribosomes on the rough endoplasmic reticulum (RER) are folded, packaged, and sorted in the Golgi apparatus. Modification, separation, and packaging of proteins and lipids for transport inside the cell or secretion outside the cell occurs in the Golgi apparatus, which is composed of flattened membrane sacs called cisternae. It takes up proteins and lipids from the ER, modifies them, and then puts them into vesicles for distribution to various cellular compartments or to be secreted from the cell.

Therefore, the correct option is D.
