Which organelles is energy released from glucose?
Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.
What organelle synthesizes sugar?
In plants and some algae, organelles known as chloroplasts serve as the site of photosynthesis. Chloroplasts contain a pigment known as chlorophyll, which captures the sun’s energy to transform water and carbon dioxide into glucose for food.

What cell structure packages proteins?
What cell transports proteins?
The Endoplasmic Reticulum or ER is an extensive system of internal membranes that move proteins and other substances through the cell. The part of the ER with attached ribosomes is called the rough ER. The rough ER helps transport proteins that are made by the attached ribosomes.
How does the cell assemble proteins?
The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression. A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time.
What is the correct order of protein synthesis?
It includes three steps: initiation, elongation, and termination. After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm. Translation occurs at the ribosome, which consists of rRNA and proteins.
Who propose the process of protein synthesis?
Biosynthesis of amino acids (the building blocks of proteins) is a complex process with many chemical reactions mediated by enzymes, which if mutated would shut down the pathway, resulting in no-growth. Beadle and Tatum proposed the “one gene one enzyme” theory. One gene codes for the production of one protein.
What controls protein synthesis in a cell?
Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins. For example, rapidly growing cells usually have a large number of ribosomes (Figure 5).
How can protein synthesis be controlled?
A key determinant of the rate of protein synthesis is translation initiation, a process regulated in part through binding of initiator methionyl-tRNA (met-tRNAi) and messenger RNA (mRNA) to a 40S ribosomal subunit. Either the met-tRNAi or mRNA binding step can become limiting for protein synthesis.
What is required for translation?
The key components required for translation are mRNA, ribosomes, and transfer RNA (tRNA). During translation, mRNA nucleotide bases are read as codons of three bases. Each ‘codon’ codes for a particular amino acid. There are also specific codons that signal the start and the end of translation.
