The post-Hundred Flowers Festival banquet, initiated by the Su family, was held in the Huanxi Restaurant in great style.
Those who came and went were all young girls and young men, not only from aristocratic families, but also from common people. All the women who participated in the Hundred Flowers Festival, including the last prostitute, were invited to come.
As for the young masters, most of them were arranged by Su Qiuyun, and some came with their sisters.
Ye Heng's situation is a bit special, as he is following his wife.
Liu Qinghuan even joked that Ye Heng should come as the boss's wife.
Liu Qinghuan specially put the tables of Huanxi Restaurant together into two long strips. Everyone who came in had to draw a strip and sit according to the number on it.
Everyone who got the slip and sat down was a little nervous and curious, wondering what kind of person would be sitting next to them. Was it a gentleman or a lady?
This was Liu Qinghuan's first large-scale blind date event. As expected, Su Qiong did not come during the event. She was just given a menu, and all other steps were set by Liu Qinghuan himself.
After all, if it is not done well, it will be a slap in the face of Huanxi Restaurant. If it is done well, the reputation of Huanxi Restaurant will spread widely.
"This Miss Su family is really generous. She actually set up this banquet in the Happy Restaurant. The decoration here is very different. I think it's better than the Misty Rain Tower."
"Shh, keep your voice down, the young master of Yanyu Tower is sitting over there." The two little girls took advantage of the fact that there were not many people around and no one had sat down yet, and they huddled together and whispered in each other's ears.
"Why is he here? There are always rumors that Huanxi brand is surpassing Yanyu Tower. Shouldn't these two families hate each other?"
"It's really a family that dares to invite and a family that dares to come."
After a long time, Su Qiong finally arrived in a formal outfit. When she passed by Liu Qinghuan, she sneered, "Why aren't you in the kitchen? Didn't I ask for you?"
The Golgi complex's most characteristic structure is a stack of several (usually 4 to 8) neatly arranged flat membrane sacs (saccules), forming the bulk of the Golgi apparatus. These saccules are often arcuate, but some are hemispherical or spherical. They are all surrounded by a smooth membrane, with no ribosomes attached to the membrane surface. The Golgi complex consists of three membranous structures: parallel-arranged flat membrane sacs, large vesicles, and small vesicles. It has two faces: the cambial face and the mature face. Proteins and lipids from the endoplasmic reticulum are transported from the cambial face to the mature face. The cis face of the Golgi apparatus is a vesicular structure, adjacent to the rough endoplasmic reticulum. The middle portion is composed of flat membrane sacs, and the transverse face is also a vesicular structure.
Saccules are the main component of the Golgi complex. They typically consist of 3 to 10 layers of saccules arranged in parallel, forming a stack of saccules. The distance between each layer is 150 to 300 nm. Each saccule is composed of two parallel unit membranes, each 6 to 7 nm thick.
Surrounding the flattened vesicles are numerous small vesicles, 400-800 mm in diameter. These vesicles are concentrated near the formation surface of the Golgi complex. They are generally believed to be transport vesicles budding from the nearby rough endoplasmic reticulum. They continuously fuse with the flattened membrane vesicles of the Golgi complex, replenishing the membrane components of the flattened membrane vesicles.
Vacuoles are often found at the expanded ends of flat membrane vesicles and may be connected to them. They are 0.1-0.5 micrometers in diameter and have a membrane thickness of about 80?.
The potential energy in the absorbent is used as the energy of the absorbing substance).
The working principle of the Ca2+ pump is similar to that of Na+K+ATPase. There is a Ca2+ binding site on one side of the cytoplasmic membrane that can bind two Ca2+ ions at a time. This Ca2+ binding activates the enzyme and allows it to bind one ATP molecule. With the hydrolysis of ATP and phosphorylation of the enzyme, the Ca2+ pump changes configuration, with the Ca2+-binding side shifting to the extracellular side. Due to low binding affinity, the Ca2+ ion is released, causing the enzyme to dephosphorylate and return to its original resting state. For each ATP hydrolyzed by the Ca2+-ATPase, two Ca2+ ions are exported from the cytosol to the extracellular space.
23. Assembly process of microfilaments, microtubules and intermediate filaments:
(1) Microfilaments: 1. Nucleation: Several G-actin proteins begin to polymerize to form a core structure;
2. Microfilament growth: G-actin is added to the polymer from both ends, with addition to the positive end being more than 10 times faster than to the negative end. (This is structural polarity; functional polarity refers to the directionality of function.)
3. In equilibrium: When the microfilaments extend to a certain period, the concentration of free actin monomers decreases to the critical concentration, the extension speed of the positive end is equal to the shortening speed of the negative end, and the length is in equilibrium (this process is called pedaling phenomenon).
(2) Microtubules:
In vitro assembly
Conditions: 1. A certain tubulin concentration;
GTP provides energy and is acidic (optimal pH 6.9);
3. Requires the presence of Mg2+;
4. A certain temperature (optimum is 37°C)
step:
Tubulin dimers form fibrils;
Multiple strands of fibrils are combined into sheets, which then close together to form short microtubules;
Dimers are continuously added to both ends of short microtubules, causing the microtubules to gradually extend to a balanced state.
illustrate:
?Microtubules have polarity, the (+) pole grows faster and the (-) pole grows slower.
?Microtubules have pedaling behavior just like microfilaments.
Most microtubules are in a dynamic state of assembly and disassembly (spindle). Factors such as low calcium concentration at 37°C favor assembly; below 4°C, high calcium concentrations favor disassembly.
