Whatever adrenaline comes into your blood you feel like energetic if that makes sense or hyper. It makes you want to do something like go for a run or jump up and down in circles you know

Proteins may be classified according to their three-dimensional shapes. Determine whether the following examples and description

m_a_m_a [10]

Answer:

-often function as enzymes or transport proteins ⇒ globular proteins

-peptide chains arranged in long strands, or fibers ⇒ fibrous proteins

-peptide chains highly folded into spherical shapes ⇒ globular proteins

-keratins ⇒ fibrous proteins

-hemoglobin ⇒ globular proteins

-water-soluble ⇒ globular proteins

-collagens ⇒ fibrous proteins

-insoluble in water ⇒ fibrous proteins

-generally function in structure and support ⇒ fibrous proteins

Explanation:

Fibrous proteins are composed by large polypeptide chains which interact each other and form large structures. They have water insoluble and have structural and protection functions- they are components of cells and tissues. Examples are: collagen, fibronectin, keratin, elastin, actin.

Globular proteins have a spherical compact structure in which hydrophobic aminoacids are buried inside the structure and hydrophilic aminoacids (which can interact with water molecules) are exposed to the exterior medium. For this, they are water soluble. They have often transport and catalytic functions. For example: hemoglobin, mioglobin, albumin, enzymes in general.

A student draws a fence with several gate as part of a model of cellular transport explain what defence indicates represent blam

Oksi-84 [34.3K]

The given question says that a student has constructed a model of cellular transport using fences and several gates.

This model can be used to demonstrate the cellular transport.

The gates of the fences can be supposed as the protein pumps and the other fence demonstrates the lipid bilayer.

Let’s suppose in the fence, there are many cattles, and outside, there are less cattles, but the student open the gate and bring more cattles inside the fence. In this case, the transport of the cattles is similar to the active transport of the molecules using protein pumps. At cellular level, the energy for the active transport is provided by ATP molecules.

Now, let’s say, the student wants to feed the cattles with some nutrition rich food, which can help in maintaining the health of the cattles. The student fills his car with the cattle food and he enters inside the fence through gates. In this case, the food was not present in the fence, but was abundant in the outside environment, so, the diffusion would occur. But food cannot come self, without help of others, so, the movement is facilitated by the car, as it is done by the carrier proteins. Hence, it is an example of facilitated diffusion.

Answer: All the water would evaporate.

Explanation: If we were closer, it would be hotter, meaning the water would evaporate.

there would be too much water - No it would evaporate

all the water would evaporate - Yes

all the water would freeze into ice - No it would be too hot to freeze

the planet would not be any different - No it would be much hotter

What will happen when golgi apparatus is removed from the cell...........??????

miv72 [106K]

Answer: all sorts of vesicle formation will stop

Explanation: If the Golgi apparatus is removed from the cell, all sorts of vesicle formation will stop. The Golgi apparatus is mainly responsible for transporting, modifying, and packaging of proteins and lipids into vesicles to be delivered to targeted destinations.
