Respiration Practice

Which molecule is the easiest to make ATP from?

• proteins

• carbohydrates

• nucleic acids

• lipds

Answer explanation

To make energy (ATP), your cells will use carbohydrates first. If carbs are not available, cells will use lipids (fat).

Which of the following is the food that's one of the inputs of cellular respiration?

• ribonucleic acid

• amylase

• glucose

• lipase

Answer explanation

Cellular respiration i making ATP energy from FOOD - which is glucose or carbohydrates.

What is cellular respiration?

• making food from other types of food

• making energy from other types of energy

• making energy from food

• making food from energy

What is the function of glycolysis?

• charge up the ATP molecule by moving electrons through the folds of the mitochondria

• break down pyruvates into electron carriers

• break down glucose into pyruvates

• charge up the electrons with the energy from glucose

Which of the following are the inputs of cellular respiration?

• water and carbon dioxide

• water and oxygen

• glucose and oxygen

• glucose and carbon dioxide

Answer explanation

Cellular respiration is making energy from food soooo it needs glucose and oxygen. (You need food and oxygen to have energy - to live.)

What is the function of cellular respiration?

• to create oxygen for other organisms to breathe

• to make food in the form of carbohydrates

• to allow the organism to breathe

• to make a high energy molecule that is usable by the cell

Answer explanation

Without cellular respiration the organism (you) cannot live. The function of respiration is to make energy from food s that you maintain homeostasis.

What is the common word for carbohydrates?

• fats

• DNA

• sugars

• oils

Answer explanation

carbohydrates = sugar = glucose
