Answer:
Please find the detailed explanation of this statement below
Explanation:
Firstly, a repressed gene is a gene whose expression has been inhibited or repressed. The lac operon in E.coli bacteria is a regulatory unit containing structural genes, a single promoter and operator regions. The promoter is the region where the transcription enzyme (RNA polymerase) binds to in order to transcribe the genes in the lac operon. The structural genes in the lac operon can only be expressed in the presence of lactose sugar.
However, in the absence of lactose, LAC REPRESSOR, which is a transcription factor (protein), prevents the binding of RNA polymerase to the PROMOTER region by binding to the OPERATOR region of the lac operon. This inhibits the expression of the lactose genes in the operon.
Note that, the structural genes in the lac operon (lacZ, lacY, lacA) code for proteins that help break down lactose sugar for energy in the E.coli bacteria. Therefore, a bacteria cell with a repressed lac operon will be unable to degrade lactose sugar.
Answer:
Aerobic respiration;this is the process of breaking down of glucose <u>with Oxygen</u> to generate energy as ATPs in living cells
Location- Matrix and inner membranes of mitochondria
Energy source_oxidative phosphorylation of glucose
Waste product-water( oxygen accept the final electron to form water)
.
38 ATPs from 1 glucose molecule
Explanation:
Photosynthesis; this is the process of reducing C02 with hydrogen ion, from water i<u>n the presence of sunlight , enzymes and green pigment chlorophyll</u> to form <u>glucose</u>
Location- stroma and thylakoid membranes of chloroplast
Energy source-photo-phosphorylation(sunlight)
Waste product-Oxygen
18ATPs

Hope it helps! :)
Hydro power because it can use tidal units to create energy to use for energy
