The substance needed for cell energy is ATP, which is short form of Adenosine Triphosphate. This is created in the mitochondria, the energy center for the cell. It is created through the process of Cellular Respiration

Active transport is usually associated with accumulating high concentrations of molecules that the cell needs, such as ions, glucose and amino acids. If the process uses chemical energy, such as from adenosine triphosphate (ATP), it is termed primary active transport.

sorry if this is too long of an answer

How can a pure white mouse help determine the genotype of a black mouse? (Hint: We cannot see genotype but we can see difference

sattari [20]

Answer:

A white mouse is purely recessive, and will produce black offspring if the other mouse contributes a black gene.

Explanation:

If Bb then the offspring will be 50% Bb and 50% bb. This is called a test cross, where we use a recessive to determine the genotype of a dominant phenotype.

The use of nuclear energy can have both positive a.d negative consequences. Which of the following is a positive consequences of

stich3 [128]

Answer:

One of the positive consequences of nuclear power plants is that it produces small amounts of air pollution. Comparing it to coal power plants, nuclear reactors has less or no production of air pollution while in operation. It is by far one of the power plants with least contribution to air pollution.

Which statement best explains how the genetic code is universal? * The shape of a DNA molecule is the same in different species.

AysviL [449]

Answer:

A DNA sequence codes for the same proteins in different species

Explanation:

All living organisms store their genetic information in DNA (genetic material). The manner through which information in the genes are encoded is the GENETIC CODE. The genetic code comprises of all the codons that specifies amino acids in living organisms. The genetic code has several characteristics, which includes that the GENETIC CODE IS UNIVERSAL

The genetic code is said to be universal because all known living organisms use the same genetic code to encode their genetic information. This means that a DNA sequence codes for the same proteins in several different species. For example, codon AUG encodes the amino acid METHIONINE in every living organism.

Please help I can’t figure this out

Ilia_Sergeevich [38]

Answer:

Photosynthesis is the process in which cells use carbon dioxide and water to make glucose in the presence of sunlight.

Respiration is the process in which glucose molecules are utilized to release energy in the form of ATP.

Explanation:

Ans1- Respiration in cells occurs in mitochondria. Cells gain energy in the form of ATP. Conversion of glucose in the form of ATP is known as cellular respiration.

Cellular respiration can take place either in presence of oxygen(aerobic respiration) or in absence of oxygen(anaerobic respiration ).

Before entering into cellular respiration glucose molecule has to be converted into pyruvic acid. This process in known as GLYCOLYSIS.

Anaerobic respiration occurs in mitochondria when oxygen is not present. It is known as fermentation.It is not effective process to produce ATP from glucose as in this process only 4 ATP can be released.

Aerobic respiration occurs in mitochondria in presence of oxygen. This is effective pathway to gain ATP as it releases 36 ATP from 1 glucose molecule.

Ans2- All cells which has photosynthetic pigments are able to use photosynthesis. Example- Blue green algae, cynobacteria etc.

Ans3- We can see different shades of green colors of plants and leaves because of different types of chlorophyll present in plant. Chlorophyll are of 6 types in plant. Their types are based on the lights they absorb. Two main types of chlorophylls are chl a and chl b.

Ans4- Both plant and animal cells have mitochondria. In plant also they need energy. To get ATP from breakdown of glucose respiration is occur in plant also.

Ans5-In photosynthesis glucose is formed from water and carbon di oxide. 6 carbon dioxide and 6 molecules of water are used to make 1 molecule of glucose. Water and carbon di oxide are reactant in this process.

Ans6 - Cells without oxygen can burn glucose to release energy. This process is known as Anerobic respiration/ fermentation. But the outcome of energy is lower than aerobic respiration. ( ANS1)

Ans7- In the process of photosynthesis reactants are water and carbon di oxide. Oxygen produced released in the form of gas along with carbon di oxide.

Ans8- The enzymatic reaction of respiration occurs in mitochondria. Krebs cycle occurs in the matrix of mitochondria.( ETC electron transport chain) to release ATP occurs in cristae of inner membrane of mitochondria.

Ans9- Plants make glucose through photosynthesis . In presence of sunlight plants use carbon dioxide and water to make sugar.
