Transition step:Each pyruvic acid molecule is transported to the __________

A one carbon molecule called _ is released from each molecule of pyruvic acid and the remaining 2-carbon unit that is formed is called ______.

CoenzymeA is then attached to _ to form __.

Additional energy is stored as reduced molecules

Answers

Answer 1

Answer:

Answer: mitochondrion, carboxylic group , acetyl group, acetyl group, acetyl CoA, NADH

Explanation:

Two pyruvate molecules remain at the end of glycolysis which still have a lot of extractable energy. The next step in storing the remaining energy in the form of ATP is oxidation by pyruvate. The transition steps are as following:

Pyruvate must join the mitochondrion, cross its inner membrane and arrive at the matrix before the chemical reactions can begin.
A group of carboxyl (one carbon molecule) is snipped off of pyruvate and released as a carbon dioxide molecule, leaving behind a two-carbon molecule called the acetyl group.
The oxidised two-carbon molecule, acetyl group attached to Coenzyme A to form acetyl CoA.
The additional energy during conversion is reduced NADH molecules and two carbon dioxide molecule.

Hence the correct order to fill the blanks is mitochondrion, carboxylic group , acetyl group, acetyl group, acetyl CoA, NADH.

What are some likely reasons the classroom doorknob is among the least infected areas in a classroom

Answers

that the doorknob isn't used that recently by students, since they don't really use that to study.

Brass doorknobs exhibit an effect known as The Oligodynamic Effect.

This property of a metal means that it will react with the amine groups of enzymes or protein found in bacteria, and kill them.

Most heavy metals exhibit this antiseptic ability.

How have changes in sea levels shaped the Earth?

Answers

as sand is moved by the ocean currents everything reshapes and builds up in specific places. its like a sand box, as you play and scatter everything into different places it changes the shape

Sea levels change for three main reasons: 1) As water warms and cools it expands and contracts; 2) The amount of water contained as ice on land surfaces changes over time; 3) The Earth's surface is dynamic and can move vertically. The first two reasons are directly caused by global temperature changes.

What types of traits can show genetic variation within a species?

Answers

Answer:

Types of variation in genetics

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring)
