The malate-aspartate shuttle enables oxidative phosphorylation by allowing electrons to be moved across the inner membrane in the mitochondrion during glycolysis in eukaryotes.
In this malate-aspartate shuttle, oxaloacetate is reduced to malate in the cytosol.
During this biochemical system process, the cytosolic malate dehydrogenase which is the primary enzyme present in this shuttle system catalyzes the reaction of oxaloacetate and NADH to produce malate and NAD in the cytosol. This system enables oxidative phosphorylation in eukaryotes.Learn more: https://brainly.com/question/17216910

What makes plant green ?
How are the life process in a cell controlled?
What gives plants cells their regular shape ?
Where are the fluids stored in the cell?
What important function does the cell membrane do ?
( can someone help me out please )
Answer:
Chlorophyll makes plants green.
Enzymes are responsible for dictating what chemical changes happen and when, so thus they control the life process of the cells in our bodies.
The cell wall is what gives a plant cell it's distinct shape (animal cells don't have cell walls btw).
Intracellular fluid, or cytosol, is the fluids stored in the Intracellular compartment.
The cell membrane is the barrier between everything inside the cell, and everything else outside of it. It protects the contents of the cell from harm and releases toxins and other waste from it. The cell membrane is basically like the gate keeper of the cell.

What is collision theory?
A.a theory stating that reactants must collide with products in order for a chemical reaction to occur
B.a theory stating that there must be minimal kinetic energy between products for a chemical reaction to occur
C.a theory stating that a chemical reaction occurs only when reactants strike each other at the correct orientation and with sufficient kinetic energy
D.a theory stating that a chemical reaction occurs only when reactants are placed in separate containers and the containers are then placed close together
Answer:
A
Explanation:
collision theory is a theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another
How to add moisture to the air without a humidifier?
There are quite a few ways to add moisture into the air without a humidifier
A few things that can help add moisture are hanging your clothing to dry. hang drying your damp clothes will add moisture to the air over time as it evaporates and it will make your house smell like fresh clothes.
Another thing is a bath, allow the water to cool off and leave the bathroom door open, the steam will add moisture to the air as the water cools.
This might seem silly but putting bowls or vases of water out on the windowsill on a sunny day mill moistens the air as it evaporates.
You can also get houseplants, moisture evaporates from the leaves and stems of plants. transpiration can help increase the humidity in your home.

Nitrogen has two naturally occurring isotopes.
Predict the number of neutrons in the two isotopes of
nitrogen, N.
How many protons?
Electrons?
Answer:
Nitrogen has 7 protons and 7 electrons and 7 neutrons.
Explanation:
The atomic number of an element is the number of electrons and protons they have. The atomic mass - the atomic number of an element equals the number of nuetrons. The atomic mass of nitrogen is 14 and the atomic number is 7 therefore we have to subract, 14-7=7.

What type of bond would be formed between hypothetical elements X and Y in the the compound XY based on their electronegativity difference?
A. Nonpolar covalent because the difference in electronegativity is greater than 0.4, but less than 1.7
B. Nonpolar covalent because the difference in electronegativity is greater than 1.7
C. Polar covalent because the difference in electronegativity is greater than 0.4, but
less than 1.7
D. lonic because the difference in electronegativity is greater than 0.4, but less than
1.7
The bond is polar covalent because the difference in electronegativity is greater than 0.4, but less than 1.7.
Electronegativity refers to the ability of an atom in a compound to attract the electrons of the bond towards itself. It is a periodic trend that increases across the period but decreases down the group.
The electronegativity difference between the two atoms as shown in the question is 1.55. This means that the bond is polar covalent because the difference in electronegativity is greater than 0.4, but less than 1.7.

What is the molarity of a NaOH solution if 48.0 mL of a 0.220 M H2SO4 solution is required to neutralize a 25.0-mL sample of the NaOH solution?
Answer:
Molarity NaOH = 0.85M (2 sig figs)
Explanation:
48.0ml(0.220M H₂SO₄) + 25ml(Xmolar NaOH)H₂SO₄ + 2NaOH => Na₂SO₄ + 2H₂O
2(molarity x volume) H₂SO₄ = (molarity x volume) NaOH
2(0.220M x 48.0ml) = 25.0ml x Molarity NaOH
Molarity NaOH = 2(0.220M x 48.0ml)/25.0ml = 0.8448M ≅ 0.85M (2 sig figs)

Explanation:
Charlotte has some copper sulfate solution. She wants solid copper sulfate. Which technique should she use?
Answer:
She should use the crystalization technique
Explanation:
First, the copper sulfate solution should be filtered to clear any impurities.
By heating the solution of copper sulfate on a china dish, the excess water in the solution evaporates and leaves behind a saturated solution of copper sulfate.
Upon cooling this saturated copper sulfate solution, crystals of solid copper sulfate will be formed on the china dish.
In solid form, copper sulfate appears in triclinic-shaped crystals.

The gases have the same P.V, T and n
R is constant AND SO constant for both
the only difference is the molar mass of the gas
for the same number of moles, the balloons will have different weights depending on the gas
so the answer is
the mass of each gas

What is buffer system ?When acids or bases are introduced, a buffer system is a solution that resists changing in pH. Acidic solutions have pH values under seven and significant hydrogen ion ( H+ ) concentrations. Basic solutions have pH values higher than seven and high quantities of hydroxide ions ( OH- ).
The carbonate, carbonic acid buffer, the phosphate buffer, and the buffering of plasma proteins make up the body's chemical buffer system.
Plasma proteins, phosphate, bicarbonate, and carbonic acid buffers are among the buffer systems active in blood plasma. By excreting hydrogen ions and producing bicarbonate, which helps keep blood plasma pH within a normal range, the kidneys contribute to the regulation of acid-base balance.
Thus, option A is correct.

for every mole of Sn2+, tere are 2 moles of Fe3+
22.4/1000L of 0.1000 M Sn2+ = 22.4 X 0.10/1000 = 0.00224 moleso there are 0.00224 X 2= 0.00448 moles Fe3+
iron atomic mass is 56
56 X 0.00448 = 0.251 gm Fe3+
so the mass % of the Fe3+ in the 0.645 gm iron ore sample is

Why is it important that you not breathe on the baking soda test?
Baking soda is a salt of sodium and bicarbonate ions. In a soda test, the breath will raise the temperature as it contains water vapor and decomposes the soda.
What is the baking soda test?The baking soda is also called sodium bicarbonate, and the test uses sodium bicarbonate as a reactant. It is also a leavening agent that is used in the preparation of food.
Breath contains some amount of water vapor that alters the test by diluting it and resulting in the clouding of the test. The water vapor decomposes the baking soda and alters the test results.
Therefore, breath contains water vapor.
