What are the answer choices?
Plant cells, but not animal cells
Animal cells, but not plant cells
Both plant cells and animal cells
Neither animal cells nor plant cells
Answer:
Both plant cells and animal cells
Explanation:
The process where the energy locked up in food is extracted take place in both plants and animal cells.This process is called Cellular respiration.It is the process of combining inhaled and diffused oxygen in the blood with assimilated food substances (glucose,amino acids,fatty acids and glycerol) to produce energy.
In both cells it takes place in the the cytoplasm and mitochondrial.
It begins with Glycolysis, followed by Krebs's Cycle..These two steps gives certain of ATPs to these cells
.However,the largest amount of ATPs is synthesized during oxidative phosphorylation for maximum of energy to be produced.This process involved the chemiosmosis where protons were diffused into the intramembranes by the proton pump (PMF) and diffused back into the matrix of the mitochondria to generate the electrochemical gradients.
The electrochemical gradients generate the energy for enzymes ATPase synthase needed for phosphorylation of ADP with Pi to give ATPs.
The oxygen act act the final electron acceptor.

Answer:
d. regulatory; operator; regulatory
Explanation:
In prokaryotes, the regulation of gene expression is done at the transcription level by operons. Examples are the lac operon and the trp operon. To initiate transcription, RNA polymerase and a DNA segment are required for binding called a promoter.
DNA segments that are close to the promoter serve as binding sites for regulatory, activating or repressing proteins. They are called operons.
The Operon is a regulatory sequence close to prokaryotic DNA that lies between the structural genes and the promoter. It is responsible for controlling the transcription of structural genes. When the repressor, encoded by the regulatory gene, binds to the operator, the promoter is blocked which prevents transcription.
The Promoter is located next to an operator and is the site in the DNA molecule that binds to RNA polymerase (which is a regulatory protein) to initiate transcription.
