Answer:
The correct statements are:
- Meiosis results in four haploid daughter cells.
- During meiosis, the 2N mother cells produce N daughter cells.
- In both processes, DNA replication must occur.
- Mitosis is responsible for genetic continuity; in higher organisms, it is essential for growth and repair.
Mitosis is a type of cell division in which a parent cell is divided into two identical daughter cells. Each daughter cell contains identical genetic material as that of the parent cell.
It plays important role in growth and repair of cells and tissues in multi-cellular organisms.
Meiosis is a type of cell division in which a parent cell is divided to produce four daughter cells. Each daughter cell contains exactly half the genetic material (chromosomes) as that of parent cells
It plays important role in the production of gametes (eggs and sperms) in sexually reproducing organisms.
Before either cell division, the DNA is replicated in the S or synthesis phase of the cell cycle.
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.
From the given balanced chemical reaction,
C + O2 -> CO2
the mass ratio of the carbon and oxygen that is needed for the reaction is 12:32. Simplifying the ratio gives 3 unit mass C is to 8 unit mass O2. Given 18 g of carbon,
18 g x (32 g oxygen / 12 g carbon) = 48 grams.
For the given product, the ratio of oxygen to carbon dioxide is 32: 44.
72 g CO2 x (32 g O2 / 44 g CO2) = 52.36 grams
Answer:
G 0 is a resting phase where the cell has left the cycle and has stopped dividing. The cell cycle starts with this phase.
Answer:
Cell surface receptors (membrane receptors, transmembrane receptors) are receptors that are embedded in the plasma membrane of cells. They act in cell signaling by receiving (binding to) extracellular molecules. They are specialized integral membrane proteins that allow communication between the cell and the extracellular space.
