Explain unsaturated, saturated, and trans fats.

Answers

Answer:

SATURATED FAT

Imagine a building made of solid bricks. This building of bricks is similar to the tightly packed bonds that make “saturated” fat. The bonds are often solid at room temperature like butter or the fat inside or around meat. Saturated fats are most often found in animal products such as beef, pork, and chicken. Leaner animal products, such as chicken breast or pork loin, often have less saturated fat. Foods that contain more saturated fat are usually solid at room temperature and are sometimes called “solid” fat.

UNSATURATED FAT

Now, imagine the links in a chain that bend, move, and flow. The chain links are similar to the loose bonds that make “unsaturated” fat fluid or liquid at room temperature like the oil on top of a salad dressing or in a can of tuna. Unsaturated fat typically comes from plant sources such as olives, nuts, or seeds – but unsaturated fat is also present in fish. Unsaturated fat are usually called oils. Unlike saturated fat, these oils contain mostly monounsaturated and polyunsaturated fat.

A few food products such as coconut oil, palm oils, or whole milk remain as liquids at room temperature but are high in saturated fat.

TRANS FAT

Trans fat can be made from vegetable oils through a process called hydrogenation**. Trans fat is naturally found in small amounts in some animal products such as meat, whole milk, and milk products. Check the food label to find out if trans fat is in your food choices. Trans fat can often be found in many cakes, cookies, crackers, icings, margarines, and microwave popcorn.

What affect do enzymes have on chemical reactions?

Answers

Answer:

Increases reaction rate by lowring its activation energy.

Explanation:

i.e If the chemical reaction completes in 5 hours it means that reaction's activation energy is very high.This factor causes decrease in rate of reaction so to increase reaction rate and to decrease activation energy enzymes or catalyst are added so now reaction will be completed in half hour.This is the importance of enzymes/catalysts.Enzyme and catalyst cann't start reaction but they increase rate of reaction and decrease time to reach equillibrium.

WHAT IS CELLULAR RESPIRATION:

Cellular respiration is the process by which living organisms obtain energy (ATP) needed for metabolic activities.

It involves the breakdown of sugar molecule (with or without oxygen) to yield energy in form of ATP and the release of carbon dioxide (CO2).

The general equation of cellular respiration is as follows:

Glucose + oxygencarbon dioxide + water + ATP.

Answers

Answer:

Absorption of food is Small intestine.

Chewing of food is Buccal cavity.

Killing of bacteria is Stomach.

Complete digestion of food is Small intestine.

Formation of faeces is large intestine.

Explanation:

Digestion is the process where larger molecules are broken into smaller pieces to release nutrients.

Digestion of food starts from the mouth especially carbohydrates. When it is consumed the buccal cavity is involved in chewing which break it into smaller pieces and the salivary gland release amylase to break it down. It then move to the small intestine where enzymes break food into smaller pieces. The stomach is responsible for killing bacteria because it is an acidic.region. when the food are broken down, the nutrients are then absorbed through small intestine and the undigested food form faeces in the large intestine.
