Anyone know about cellular respiration? Please help me label, 60 points!
matrenka [14]

Answer:

Mitochondria- glycolysis

ATP synthase- converts ADP to ATP

Inner membrane- electron transport chain

Matrix- krebs cycle

Explanation:

The mitochondria forms the fundamental site for glycolysis. The glucose is broken down enzymatically to produce carbon dioxide, water and ATP. The krebs cycle is the first stage of aerobic respiration. It takes place in the mitochondrial matrix. ATP synthase is an enzyme that generates ATP during the process of cellular respiration. ATP synthase forms ATP from ADP and an inorganic phosphate (Pi) through oxidative phosphorylation. The mitochondrial inner membrane is the site of the electron transport chain, an important step in aerobic respiration.  Energy obtained through the transfer of electrons down the ETC is used to pump protons from the matrix into the intermembrane space, creating an electrochemical proton gradient generating ATP.

The lactose (lac) operon in E. coli is an example of a repressed gene when lactose is not available in a cell. In 3-5 sentences
irakobra [83]

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.

Each row in the auditorium has 18 seats and 246 and teachers are going to watch an assembly in the auditorium how many rows of s
Romashka-Z-Leto [24]

13

Explanation:

We will divide the total number of the teachers (246) in the auditorium with the maximum number of seats per row (18) to determine how many rows are completely filled;

246/ 18  = 13.6667

We are only interested in rows that are completely filled which is the whole number;

= 13
