The manner in which several different ions and molecules move through a cell membrane is shown in the diagram above. For each lon or molecule, the relative concentration on each side of the

A
Glucose is transported into the cell by active transport
Subm
B
Nat is transported into the cell by active transport
с
The movement of glucose through the membrane requires ATP hydrolysis
D
Na transport out of the cell requires ATP hydrolysis

Answers

Answer:

The correct answer is - D . Na transport out of the cell requires ATP hydrolysis

Explanation:

Sodium-ion moves or transported from the inside of the cell to the outside the cell by the process called active transport. Active transport takes place takes place when the movement is against the concentration gradient to a higher concentration area through the cell membrane.

Active transport requires energy in order to transport the molecules or ions from low concentration to high concentration. In sodium-potassium pump get the energy from the hydrolysis of the ATP.

The given diagram represents the transport of sodium out of the cell using active transport. Active transport utilises the energy or ATP released during respiration. The correct answer is that sodium is transported out of the cell requires ATP.

Active transport is defined as the transport in which molecules move from lower to higher concentration, against the concentration gradient. The active transport requires the hydrolysis of energy to move across the cell. The sodium-potassium pump follows the active transport, such that:

The pumping of ions against the concentration gradient requires the addition of energy. The high-energy molecule is used to facilitate the active transport of sodium ions during the sodium-potassium pump.

Therefore, the image represents the sodium is transported out of the cell by active transport.

Aerobic respiration has 3 stages: glycolysis, Kreb's cycle, electron transport
chain. What happens in each stage? How many ATP molecules made during
each stage?

Answers

What happens in each stage?

GLYCOLYSIS: "In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. In the end, it gets converted into two molecules of pyruvate, a three-carbon organic molecule. In these reactions, ATP is made, and NAD+ is converted to NADH." (Khan Academy)

KREB'S CYCLE: "This is a central driver of cellular respiration. It takes acetyl CoA—produced by the oxidation of pyruvate and originally derived from glucose—as its starting material and, in a series of redox reactions, harvests much of its bond energy in the form of NADH, FADH2, and ATP molecules. The reduced electron carriers—NADH and FADH2—generated in the TCA cycle will pass their electrons into the electron transport chain and, through oxidative phosphorylation, will generate most of the ATP produced in cellular respiration." (Khan Academy)

ELECTRON TRANSPORT: "In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient." (Khan Academy)

How many ATP molecules made during each stage?

GLYCOLYSIS: 2 ATP

KREB'S CYCLE: 2 ATP

ELECTRON TRANSPORT: 34 ATP

Khan academy is the best for breaking down processes in chemistry! I used khan all the time when I had trouble understanding chemistry last year.

Hope this helps! Please correct me if im wrong!

Stage 1: Splitting Glucose stage
The word glycolysis initially means “glucose splitting,” which is exactly what happens in this stage. Enzymes split a molecule of glucose into two molecules of pyruvate (also known as pyruvic acid).

Stage 2 The Krebs Cycle

Recall that glycolysis produces two molecules of pyruvate (pyruvic acid). These molecules enter the matrix of a mitochondrion, where they start the Krebs cycle. This cycle is at the center of cellular metabolism, playing a starring role in both the process of energy production and biosynthesis. It finishes the sugar-breaking job started in glycolysis and fuels the production of ATP in the process. It is also a central hub in biosynthetic reactions, providing intermediates that are used to build amino acids and other molecules. The citric acid cycle enzymes are found in all cells that use oxygen, and even in some cells that don't. The examples included here are taken from several different organisms.

Electron Transport Chain Stage.

The electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that drives the creation of adenosine triphosphate (ATP). ATP is used by the cell as the energy for metabolic processes for cellular functions.

The lac operon is regulated by both the availability of lactose and glucose. How does E. coli regulate transcription of the lac operon?

Answers

Answer:

E. coli regulate transcription of the lac Operon through the production of a small molecule called cyclic AMP (cAMP).

Explanation:

The lac operon is regulated by both the availability of lactose and glucose. E. coli regulate transcription of the lac Operon through the production of a small molecule called cyclic AMP (cAMP).

This cAMP acts a signaling agent which is made by E. coli anytime glucose levels are low In the cells which helps regulate the transcription process as glucose is needed for it .
