Answer:
A
Explanation:
Golgi apparatus is an organelle in eukaryotic cells that stores and modifies (might include addition of sugar groups) proteins and lipids for certain functions and prepare them for transport to other parts of the cell.
In the Endoplasmic reticulum, proteins fold into into their correct shape. Some of them are transported to the Golgi apparatus in membrane vesicles. Some proteins need to do their jobs in the Golgi (they are said to be Golgi-resident). They are transported from the golgi appratus to their final destinations through a secretory pathway. It involves sorting proteins into different kinds of transport vesicles, which emanate from the trans Golgi network and deliver their contents to the appropriate cellular locations.
Proteins that are membrane embedded are conveyed to the plasma membrane (integral membrane proteins) by constitutive secretion. Proteins can divert from constitutive secretion pathway and be targeted towards other destinations such as lysosomes (as lysosomal proteins) and regulated secretion from cells (to the cell exterior).
A substance that modifies the transition state to lower the activation energy is termed a catalyst; a catalyst composed only of protein and (if applicable) small molecule cofactors is termed an enzyme. It is important to note that a catalyst increases the rate of reaction without being consumed by it.
Answer:
Power is the amount of work done in a certain period of time.
we also know there is a formula: Power = work done / time elapsed
Answer:
Electron transport chain is the last step of respiration.
Explanation:
Respiration is a cellular process in which glucose molecule is broken down into carbon dioxide, water and ATP is produced as end product. Respiration consists of following main steps:
1. Glycolysis:
It occurs in the cytoplasm of cell, and each glucose molecule is converted into two pyruvates with help of ATP.
2. Formation of Acetyl coenzyme A:
It is a connecting link reaction between glycolysis and Kreb cycle. In this phase Each pyruvate react with Coenzyme A to become acetyl coenzyme A.
3. Kreb Cycle:
It occurs inside mitochondria. In this cycle each acetyl coenzyme A with fixed with CO to produce citrate which undergo in a cyclic reaction to produce ATP and NADH. .
4. Electron transport chain:
It is the last step of respiration which complete in mitochondrial membrane. In this phase most of the energy is produced along with H₂O as by product.
Conclusion:
It was concluded from the above discussion that the last process that takes place in respiration is electron transport chain.
Answer:
meiosis 1, anaphase
Explanation:
Meiosis is a type of cell division that consists of two rounds of cell division known as Meiosis I and Meiosis II, and one round of DNA replication, thereby the resulting cells (gametes) contain half of the genetic material found in somatic (body) cells. Both Meiosis I and Meiosis II can be divided into the following phases: Prophase, Metaphase, Anaphase, Telophase and Cytokinesis. Alleles of a gene separate during the anaphase of Meiosis I (i.e., Anaphase I), because homologous chromosome pairs separate during this phase of the cell cycle.
