What is a reducing sugar?

Answers

Answer 1

Answer: Reducing sugar is any sugar (all monosaccharides, some disaccharides, oligosaccharides, and polysaccharides) that is capable of acting as a reducing agent because it contains free aldehyde group or free ketone group.

Aldehyde group or alkanal is an organic compound containing formyl group. The formyl group is a functional group consisting of a carbonyl center bonded to hydrogen and an R group. This group can be readily reduced to primary alcohol with the help of catalyctic hydrogenation either applied directly or by transfer hydrogenation.

Ketone group unlike aldehyde group does not have a hydrogen atome bonded to the carbonyl group but it can still be hydrogenated.

What happens to an enzyme after it catalyzes a chemical reaction?

Answers

An enzyme remains unchanged after it catalyzes a chemical reaction.

What is an enzyme?

An enzyme is a biological catalyst that regulates the rate of biochemical reactions in living systems.

Enzymes aid in the occurrence of certain reactions in the body. That is, some chemical reactions cannot occur without specific enzymes.

Enzymes act by binding their active site to the substrate. However, they remain unchanged after the reaction i.e. can be reused.

Therefore, an enzyme remains unchanged after it catalyzes a chemicalreaction.

The shape of the enzyme will be changed by the presence of two or more chemical reactants. Then the enzyme catalyzes the reaction. After the reaction is catalyzed, the producet will be released. Then the enzyme will be able to relax. So this means that the enzyme is back to its normal shape and it will get ready to do it again.

Which of the following options correctly describes where pinocytosis occurs? A. All eukaryotic cells B. All prokaryotic cells C. Mitochondria of all cells D. None of these

Answers

The correct option is: A. All eukaryotic cells.

Pinocytosis is a form of endocytosis where a cell engulfs small amounts of extracellular fluid, along with any dissolved solutes present, by forming vesicles from the cell membrane. It primarily occurs in eukaryotic cells.

Which Best Describes why Plant cells have chloroplasts and animal cells do not A- Plant cells need chloroplasts to make DNA because most plant cells do not contain a Nucleus

B- Plant Cells need chloroplasts to make food because most plants cannot move to get there food on their own

C- I dont know

D- Plants cells need Chloroplasts to move materials in and out of the cell because most plants cells do not Contain a Cell Membrane

Answers

Answer: D

Explanation: Because The Chloroplast is the Gate to move waste out of the cell and nutrients into the cell. Most plants do not contain a cell membrane.

Animal cells have a chloroplast and plant cells don't have a chloroplast because plant cells uses the chloroplast to produce energy from the chloroplast. So, option B, i.e., plant cells need chloroplast to make food because plant cannot move to get their food on their own, is correct.

The plants produce energy or their food with the help of a process known as photosynthesis.

The chloroplast is a green colored cell organelle which is responsible for carrying out photosynthesis.

In the photosynthesis, the light energy from sun is converted into chemical energy which is utilized as food by the plant.

Therefore, option B, plant cells need chloroplasts to make food because most plants cannot move to get food on their own.

What processes can transform metamorphic rock into sediment? A.
weathering and erosion

B.
heat and pressure

C.
compaction and cementation

D.
crystallization and solidification

Answers

Sedimentary rocks are formed by the deposition and successive cementation of material at the Earth’s surface and within bodies of water. They form layers called strata which can be seen in exposed cliffs. Example of sedimentary rocks includes limestone, sandstone, mudstone, greywacke, chalk, coal, claystone and flint. Limestone from metamorphic rock marble when subjected to extreme heat and pressure over time. Sandstone forms the metamorphic rock quartzite. Mudstone forms the metamorphic rock slate. Flint is a hard, sedimentary form of the mineral quartz. The answer is letter C.
